well u dont need to test for ammonia and nitrite once your tank is cycle. You do need to test for nitrate but not daily test and also nitrate won't affect too much for fish mostly affect on corals and anemone. Personally I do weekly test or one in every two week for phosphate. You can do two week test for alk, cal and mag when you want to do automatic dosing. I don't worry about nitrate because i have skimmer and weekly 10-20% wc (depending on how i feel, if i feel lazy i do 10% otherwise 20% wc).

Dark Helmet, Asking George; a guy who knows what he's doing, is research. I don't google anything before I ask someone I trust, any moron can put anything on the internet. Thank you Jeremy Non and Tbomb for your useful info, I'm looking forward to the hobby! :) Let me elaborate on the clownfish, I'm looking at Amphiprion ocellaris species. Any more advice would be awesome. Thank you guys.
Jeremy Non
Jeremy Non - 7 years ago
LAWSICK1 it could depend on a few things. what is next to the torch coral? if there is nothing next to it, make sure that you are not giving it too much flow. too much flow can cause the tentacles to run against the rigid skeleton and can cut them and they will die off. also check your calcium levels. make sure the torch is in enough light to keep it happy but not too much light.
LAWSICK1 - 7 years ago
CoralFish12g I have question , I have this torch coral that seemed to be doing well until the tentacle tissue started to fall off, do you know why this would happen? I noticed the end of the skeletol structure where the tentacles retract at night look like it's slowly crumbling away and it causing the coral to lose a head. I do weekly 7 % water changes in hope of not adding additives.
Tbomb - 7 years ago
@Dark Helmet Calm tf down. He's doing his research rt now by asking us. How does online forum works?! People ask question and other who know the answer reply. It's good to ask a question before purchasing live stock.
Jeremy Non
Jeremy Non - 7 years ago
Dark Helmet lol "I'm all high and might because someone made a mistake" grow tf up and besides he was talking mainly about researching things to avoid having a tank with issues. so if you didn't mix species of clowns then nothing bad will arise from that.
Tbomb - 7 years ago
well lets see. Depending on what kind of clownfish you want. If you have maroon and you put it in first, then you will have trouble because maroon is the most aggressive and very territorial clownfish in the family. If you want maroon, I highly suggest to put maroon last cuz they will kill other tankmate. But for percula and ocellaris clownfish, you can put any fish you want. Its best for you to go to Liveaquaria.com to see what's their recommended tank size for each fish. Also depending on what do you want in the tank. If you want to have semi to predator tank, you can get eel, and dwarf lionfish with maroon clownfish. I have 55g with clarkii clownfish baby, one spot foxface, three stripped damsel, and bi color. In my qt, i have 4 banggai cardinal and sailfin blenny.

Okay. Thaks guys. So what other fish can I put in a 73 gallon with 2 clownfish?
Tbomb - 7 years ago
Yes you can that's why you have many designer clownfish like snow onyx, black ice and fancy white from this crossbreeding. Only Ocellaris and percula clownfish can crossbreed together. I don't know about other clownfish breed.
Jeremy Non
Jeremy Non - 7 years ago
Yea very true about the maroons...and really? I was always told not too mix percs and o.c. I guess you learn something new every day lol
Tbomb - 7 years ago
Even having 2 maroon, it still be very difficult because maroon never back down from a fight for submission issue. If you really want maroon, I recommend get one big maroon around 3" and one small juvenile maroon around 1" that way they have higher chance of having maroon pair. Jeremy you can mix ocellaris and percula clownfish no problem. But you don't want to mix ocellaris with maroon, tomato, or clarkii.
Jeremy Non
Jeremy Non - 7 years ago
Christopher Hamilton. you can put 2 of the same species together (like 2 maroons or two false percs or 2 percs. I wouldn't mix them. they are fine when they are younger but will become very aggressive later on. if you want more than 2 clowns of the same species you have to do a harem tank ( at least 10 to 15) of them. however, you can house as many juveniles as you want together but they might only be peacefull for a year or so
Tbomb - 7 years ago
Clownfish you need to be the same species even so some clownfish will fight will kill each other even they're the same family like maroon, tomato, and clarkii family. If you want to have mix clownfish, then I recommend percula and ocellaris clownfish. You cannot have more than a pair in small tank. Also you cannot mix clownfish like ocellaris with maroon in small tank. You can get away with multiple mix clownfish as long as you have big tank and enough territory for them to claim.

George my name is George too and I love this video. If things aren’t perfect refer to Water Change. My goal is to have salt water compatible equipment but start keeping a more demanding fresh water species. All Tropheus species are challenging to keep for any aquarist and also Pseudotropheus Saulosi or Demasoni. If I can keep these fish thriving and at least proved a pure enough environment for them to breed, I then should think about moving up to salt water. I don’t recommend under any circumstances of anyone to start salt water without at least having freshwater experience for a while.

I find that most issues do stem from both overstocking and lack of water changes or both.basically if you don’t have a lot of time to keep up with your tank your wasting your time.a lot of people want that eye popping tank but then don’t have or are too lazy for testing and maintenance.

Hi coral fish 12g
can i ask you a question?

I want to have a nano reef tank from my 11 gallon aquarium.
My question is - did i need a RODI Machine for success nano reef tank?
Or i need just a good salt?
thank you!

Water changes are not always the answer. If you do a 20% water change, you've only removed 20% of any nutrients present in the aquarium. As for Cyano or Hair algae, best to just leave it, it will disappear in the end. Also if you have completed a water change and Cyano comes back, the water you are using for water changes is probably adding something undesirable to the aquarium.

Why have I never gotten bubble algae, Dinoflagellates or anything like that? The most I've gotten is diatoms or a small amount of cyano. Maybe it's because I don't have live rock? I just have a TON of live sand. Also no coral. Just fish and inverts. Either way I'm pretty lucky.

De'Mario's Reef aquarium
De'Mario's Reef aquarium - 6 years ago
My main issue is damn brown algea ..I am using a four stage ro/di..Water parameters are on point.my 90 gallon is running now for over 2 years and my 35 cube was originally a 20 gallon long.Using aquaforest reef salt.I have uv full spectrum lights that stays on for about 10 hrs daily.I faithfully do h20 changes as required.only supplement I add is acropower and Kent Marine essential elements. Ocean revive LEDs on my 90 and AI prime on the cube..Any suggestions.
SomeDumbGamer - 6 years ago
De'Mario's Reef aquarium your fish will do just fine without food for three days. But you can still leave your filter and skimmer on. All you need to shut off is the UV and Lights. Also from now on I would shut off the lights at night. So that way it would mimic today night cycle and help with the algae.
De'Mario's Reef aquarium
De'Mario's Reef aquarium - 6 years ago
SomeDumbGamer one more ??.when dosing acropower,leave my skimmer running or turn it off..once I do the 3 day blackout..

De'Mario's Reef aquarium - 6 years ago
SomeDumbGamer ..thank you for your Swift response..Really appreciate your advise,cause I am still in the learning and tweaking phase..will turn off both uv on both systems and do a 3 day black out....,can my fish go 3 days without food though.
SomeDumbGamer - 6 years ago
De'Mario's Reef aquarium well, I would definitely shut off the UV for a while. Algae loves UV and it may also be due to high TDS or total dissolved solids. Algae like diatoms or brown algae thrive on silicates which can't easily be removed unless you use RODI water. Which you probably do. So I would shut off any UV or lights in the aquarium. And then put a dark towel over the tank for about three days. It may work. Check out some videos on it!
De'Mario's Reef aquarium
De'Mario's Reef aquarium - 6 years ago
SomeDumbGamer ..another ?.when using acropower do you turn off the protien skimmer and the uv..Nothing mention about this on the companies product bottle.
SomeDumbGamer - 6 years ago
De'Mario's Reef aquarium not sure. But ide say it may be due to the lights. Since algae thrives on light I would shut the lights off for a few days and maybe it would help?

I am not sure I agree with the water changes being the answer to problems. If your water is getting out of control it's because you're either doing too much of something or you're not doing something that you should be doing. The Triton method, which is very successful, is based on the idea of never doing a water change.

I think just what you mentioned is a lot of it but also the lighting, bioload, and feeding schedule has a lot to do with it as well. There are a LOT of ways to run a reef tank. You just have to figure out what way works for you. Personally the single biggest thing that helped my tank look MUCH better was my lighting(quality and amount) and monitoring calcium and magnesium especially. I ran into dinoflagellates pretty bad(looked like algae there was so much of it) and I significantly cut my lighting time and stopped doing water changes(to starve them of nutrients) and my tank has never looked as good as it does now. Corals are all growing(softies, LPS, SPS...have had to dose calcium and magnesium). I plan to just keep doing what I'm doing and observe the tank over time. I've found that listening to how your tank is reacting is a great way to get a sense of things, just like checking parameters. Taking the time everyday to sit and look at your tank for more than a few minutes at a time is not only enjoyable and relaxing but allows you to realize things.

I have a really successful reef tank that hasn't had a water change in 3 years now not saying to go and say hey I don't need to change this water because yeah I know water changes are a pain but this tank has been running for so long it's a 29 Coralife BioCube it's drilled and the whole entire stand is practically a sound no I don't know how but it's now self-sustaining and it's been that way for about 3 years it baffles me sometimes on how this little ecosystem in my tank unfolded but I will admit it was my first tank and man was there a lot of mistakes a lot of problems and one of the things I've also think should have been left out it might be your lighting if your reasoning stock lighting from a tank that comes with lights such as the Coralife BioCube will I know they have a new LED lighting for their newer models today but I got this one these things first came out and the lighting sucked the picture on the box showed a beautiful reef tank but the lighting did not match up it looked terrible I took off the lid and the rim just because I wanted it to look aesthetically pleasing also a thing that can make your tank look horrible in my opinion would have to be those stupid magnet scrubbers I got little bits of sand stuck in mine and it left horrible scratches on the glass I am currently going to be moving this aquarium to a 65 gallon that I bought months ago saving up money for supplies surprisingly my first fish I got for my 29 gallon BioCube is also still alive who knew clown fish can live that long LOL but with this new tank I'm hoping they're not have any of the same mistakes that I made on this little tiny 29 gallon BioCube

You guys, myself included, have it easy these days with LED lights, captive raised and incredibly tough fish, tough coral frags harvested in captivity, built in all-in-one filtration systems, cool new biological media, etc.

Around 15ish years ago, just for shits and giggles, I set up a 42 gallon corner aquarium and built a reef from scratch. It was up and running for 5, maybe 6 years before I broke it down and donated all the corals, inverts and fish (including captive bred Ocellaris, 4 or 5 out of 30 or so actually survived to adulthood). Rarely did water changes, only topped it off once every few days with filtered tap water and some Kalkwasser thrown in. I changed out the active carbon a couple times a month, and occasionally cleaned the viewing surfaces with a paper towel (it barely needed any cleaning). It ran on a Magnum canister filter and an Emperor 250, with 4 normal 20" flourescent lights (2x2500k "daylight," and 2x 10000k actinic) Everyone laughed at me saying it couldn't be done without drilling, installing a drip sump, RO/DI, a skimmer, a refugium, expensive live sand, metal halide or high output fluorescents, a chiller, tons of powerheads and wavemakers, a quarantine tank, billions of supplements, etc. Little did the haters know I had been in the aquarium hobby since I was 5 years old breeding guppies and various other mollies/platies, as well as the occasional killifish (they were hard to come by then). I probably still have some pictures saved somewhere taken on a top of the line Motorola SLVR, which was the first camera and first camera phone I'd ever owned.

Keep it simple and pay attention to what's happening in there and your reef will take care of itself with very little influence. I see way too many people overreacting and doing supplements on top of supplements, constantly fiddling with heat, lighting, feeding, excessive water changes, etc. When a reef starts experiencing far too much outside influence, the results are consistently negative.

I try to apply to apply these principles to my hobby. While I am an experienced fresh water hobbyist the marine environment has always been a bit daunting. I finally took the plunge and, while I have my trials and tribulations, it is slowly congealing and making sense. On a side note, I love your perseverance in the hobby and get a great deal of satisfaction comparing your very early videos and watching the maturation and development of a young man from a kid to a maturing educator.

omg, P R E A C H!

as someone who works at an LPS, I can't even begin to count how many customers' problems stem from too few water changes! K have one guy who actually brags about not doing water changes.
(for some reason, his reef tank is no more... hmmm, can't imagine why?)

one regular customer was trying to figure out why his system was crashing. turns out it had been weeks since his last water change, and he hadn't even touched his filter (media included) in 6 months!
a large water change and a good filter cleaning and media change and his tank is beautiful once more! Too bad it took a fish dying for him to pay attention. :(

You suck George! I mean that in the most sincere way! I've been in the hobby for 20+ years (since 10) freshwater. Until i saw one of your vids a year and a half ago. I went saltwater after that. Now im addicted. Weekly water changes and my fish could not be happier. Its been a journey and i love it. At my lfs i amaze them with all the knowledge i have gained from your vids. PLEASE keep it up and thank you!

George you hit the nail right on the head with water changes. I have been reefing since 2014 and I am no expert but I religiously do a 20% water change every week and I couldn't be happier with my tank. I also subscribed to your channel a month into the hobby.

3 reason your tank looks horrible
1. you feed youre fish too much
2. you dont do enough water changes
3. You messed up cleaning your filter.
In my opinion testing the water is not very useful. He is right about water changes though. If you see even one unhappy coral ,excess algae, or any abnormalities, do a water change! It always leads to a water change.

More reasons
.change carbon
.get a ro/filter
.air bubbles in tank
.too much light
.clean your tank (every inch of it)
.switch the flow to push fish poop off the bottom of the aquarium.
.rotting fish or invertabrate in tank
.clean your sand
. not enough filtration

hey dude, thanks for the cool videos. i wanted to ask whats your input on green coralline algae? i had to take down my 60 gal setup cause i moved and i ended up making a smaller about 20 gal tank plus sump. i ran into the issue of green coralline algae growing and i don't know what causes this. i have a gen 2 radion that i have running i think about 30% compared to the 60% i had on the bigger tank. could this be the problem?
Natural Vivaria
Natural Vivaria - 7 years ago
Water changes definitely help, but a lot of those SPS reefs you showed as examples of amazing reefs from seasoned hobbyists definitely dose, rather than relying solely on water changes. The calcium, alk, and magnesium consumption level of densely packed SPS reefs is so high that without a calcium reactor or dosing liquids, you simply won't be able to sustain them without extremely large daily water changes. Many of us with SPS reefs experience drops in Alk and Cal over the course of a day, and a small water change every couple of days won't 'reset' the tank. The 'perfect' water you are adding back to the tank, regardless of the salt mix, will end up diluted by the remaining water in the aquarium, and the levels will be much lower than what is optimal.

Even in a 20 gallon SPS reef I did weekly water changes on using Aquavitro Salinity [salt mix] still needed a 3 channel auto doser that added a generous amount of Cal, Alk, and Mag solutions daily in order to maintain optimal growth and color of the corals.

All in all, your video is great and I do agree that more water changes are definitely required, I just think suggesting that it resets your aquarium is a stretch, and can be really misleading for those newer hobbyists that want to achieve the sorts of SPS heavy reefs you showed as examples.

Sub'd though, so keep it up!

thatReefGuy - 7 years ago
While that is true he specifically said he was talking to inexperienced reefers that had a tank that looks like the first pic (NOT all the Acro tanks that came after that). Those people with THOSE Acro Tanks know what they are doing and have no need to watch this video. They Video was aimed at the 90 Percent of people that don't have Acro Tanks. Although I believe in testing and dosing like you do this video was not geared towards you. I have one Tank That I never Dose because it is all Zoanthids yet. I have another Tank that has to be tested and dosed 2 to 4 times a day. Every Tank is different. I guess what I am saying is even though you right every tank is different. Don't look at your tank and how you have to do it but what his target audiences tanks look like and their experience

When I first got into this hobby, and saw all the expensive reactors and different methods of filtration, I was shocked and asked my dad "why don't people just do more water changes?" His reply "because people are lazy." So true. People ask me so many questions about my tanks, until they see how basic the set up it, then they think I must not know enough and they stop asking questions. A successful tank doesn't need to be complicated.

Love your Chanel. One note is I called the company after seeing your clip and most of the testers are ment for freshwater. They said that the will give inconclusive readings for salt water. PH phosphate and alkalinity are about the only ones that you can use for a saltwater tank. Quick question my start up tank is getting brown algae growth. Do I need to introduce Coraline algae to the tank and if so what are the benefits. I am using RODI system, nitrates are zero phosphates are low working on them. Looking forward to starting corals

I'd add to this in saying that when doing a water change you really need to make sure the water you're putting in is mixed properly and to the right levels. Too many water changes with good water aren't bad but you can really screw things up if you don't mix it correctly...

Um no. If you know what you are doing and have friends in the hobby to help you out you can buy frags fro cheap and grow them out. Yes, it could cost 20,000 but if you know what you are doing and no where to look it will be a fraction of that. But it still will take a while to grow it.

Evaporative cooling. Get your tank to evaporate as fast as possible, it will cool it down. Of course you will need a good and reliable top up system for this to work or your tank will get super high salinity. Basically get a fan to blow on the surface of your aquarium and replace the evaporated water with new fresh water.

You are completely rite. I had very high expectation. Reef keeping is time consuming but at the same time u have to learn from your failures and keep researching to make it better rather than giving up. I crashed my tank twice but now after learning I am doing good. Knowing all my water parameters. But I wanna ask u a question I have 3 fishes in my reef but whenever I add the 4 th one it always dies. I have a 10g aquarium. I have a lot of Copepoda so I got yellow wrasse and it perished within a week. My parameters are good. Any suggestions. Your suggestions helped me out a lot in growing my corals.
fishtankfreak - 7 years ago
Hmm...Interesting, usually two spot wrasses (they don't usually have much yellow on them) are tough to find in the hobby as they are not often suitable for home aquaria. Could it have been a Twinspot Hogfish? Those are often mistaken as a wrasse.
Viggy Iyer
Viggy Iyer - 7 years ago
fishtankfreak Ohhh. I am talking about yellow two spot wrasse. I have 2 peculiar clown and a purple flame goby. I have 2 turbo snails and one red cherry shrimp. I was jus thinking of adding one more fish lol.. Hope i find a suitable one. U have any suggestions..
fishtankfreak - 7 years ago
Hey! I'm not George, but I am willing to offer my advice. Depending on the fish that you currently house it may be the tops for your tank. Depending on the fish you are looking to add, it may not be a suitable environment causing stress. I'm not sure which type of wrasse you have described, as yellow wrasse could mean many things... Sometimes a tank like the one you have described is only equipped to handle a certain amount of bio load (fish, inverts, ect...). Granted, increasing filtration efficiency and/or size may help but is not likely worth it. In my opinion, a mandarin is a great although they can be tricky to care for it may be best to avoid them until you can add them to a larger environment where they have more room to hunt and sustain themselves. Just my 2 cents. Happy fishkeeping!

AzraelThanatos - 7 years ago
As a major thing, you can actually do to many water changes.

If I remember right, be very careful of going beyond a total of 60% in under a week. If you take to much out, you can kill off your fish because you've removed far to much of the bacteria you need. A friend of mine had his tank crash because of that one when he had a small issue and went for a few to many emergency water changes repeatedly and the load kind of murdered the system...
