Calcium Spike / Alkalinty CRASH - in Reef Tank

After refilling my alkalinity jug, I inadvertently caused a loop in the supply line and thus cut off all alkalinty to the reef tank. This of course crashed my alkalinity but also spiked my calcium! In this video I take you through the steps I used to remedy the problem. Here is the Randy article: http://www.advancedaquarist.com/2002/11/chemistry

would the same process be the same if alk got very high? would you take alk off line and keep calcium on?

Hello nice video, sorry about the tank crash friend, but you can't throw the towel after so much, you can always start different, Good luck anyway.
Hey I saw that bucket of alkalinity product, could you please let me know what brand is it? Also the same with the Calcium? I want to start using these things buying by the bucket in my 90 gallon and how do you prepare the solutions.
Thank you so much for the help and tips.

Talk to us. Don't just ignore the fact that this vid is wrong. It is clear from the last part of the video your tank is losing 10ppm calcium per day. So the rise of 90ppm calcium is clearly an overdose.
Annie Duncan
Annie Duncan - 3 years ago
Just a thought. Look at it like this. If you did not dose any calcium when your carbonate stared to drop, then you would have lost 10ppm calcium. Your calcium would have gone down from 420 to 410 ppm. Would you have dosed 100 ppm calcium to get your calcium levels back up to 420. No you would have dosed 10ppm calcium. Some how 100pm was dosed. We all make mistakes. Me included.

A reply on reef central by a leading reef chemist and, reef central moderator said you are Wrong. No where in Randy's  articles does it say this. Think about it. If your test kits are right, then your tank was overdosed  by 90ppm calcium. Where did it come from the reef fairy!!. Most likely faulty test kit, or faulty dosing pumps.I have dosed alkalinity with out calcium before and have never had a problem. My concern is new reefers getting wrong, and confusing information.  I saw a post by Randy on reef central, about dosing bionics 2 part separately. He said there was no problem.

Am I the only one who is totally confused here. Why does the calcium shoot up if you stop dosing alk.  Did your corals suddenly stop growing.  That's a lot of calcium to overdose. My head is going round and round. Where does Randy say your calcium will go up.  Sorry to be so negative.
Annie Duncan
Annie Duncan - 3 years ago
Look at it the other way round. If 90 ppm was the correct dose to keep  calcium levels stable, then you should have lost 13 dkh (not possible I know, but in theory you should have lost 13 dkh ), to make calcium carbonate. You only lost 1.4 dkh.
Annie Duncan
Annie Duncan - 3 years ago
This only lead to an imbalance because your doing pumps overdosed calcium. Your alk went down to 8.1. Your dosing pumps should have dosed 10ppm calcium, to form calcium carbonate with the 1.4 dkh that was used/lossed.  For every 10ppm calcium, you need 1.4 dkh to make calcium carbonate.If your calcium was 420ppm, then it should have remained stable, if you were dosing the correct anount. 8.1dkh, and 420ppm are in the safe zone and so still balanced. Your dosing pumps are faulty, you made a mistake with the apex, or your test kit is faulty.
Klem Reefing
Klem Reefing - 3 years ago
This is a 2 part situation meaning that two things(Ca&Alk) are on automatic timers(apex). When one stopped dosing(alk) the calcium kept dosing on schedule thus leading to the imbalance...

do you not have the Achilles Tang anymore?
Klem Reefing
Klem Reefing - 3 years ago
The reason, in my opinion, is that it is almost impossible to keep ick
out of your tank and when that happens - they are the first to go
because of their thin slime coat. UV helps a lot, as does quarantining
EVERYTHING, but its very hard to keep that fish. Im sure I will try
again but right now is not the time for me.

Klemmetsmo Reefing I am really sorry to hear that. The Achilles Tang is my dream tang, but im to scared to buy one. I was curious to see if it worked for you as I have a similar sized tank.
Klem Reefing
Klem Reefing - 3 years ago
Unfortunately it died.... I havent decided if Ill get another. Powder Blue and Achilles seem to have a very thin slim coat, more so than the already thin slime coats of other Tangs...

great video. So you simply slowly added alk and stopped adding cal. until the cal went down and the alk rose. I guess i was under the impression that you were not suppose to dose unequal amounts of 2 part. I does totally make sense I just thought it was always suppose to be equal. Love you work.
Klem Reefing
Klem Reefing - 3 years ago
You are supposed to dose equal. The reason is because of the inverse relationship between the two. That means if you increase one - it reduces the other. So if you are not dosing equal, then you are creating an endless struggle for stability in your tank. However, in this situation, there was already an imbalance so I used this inverse relationship to my advantage and brought the CA level down slowly. Wall-Law :) Make sense?

Nice video and explanation, I have the same containers for my dosing solutions. I put a length of 3/4" PVC down in the opening, extending towards the far bottom corner. Then the tubing from the pump goes in the pipe. This way the tubing stays straight and always at the bottom.

good old weekly water changes = nature for me. never any dosing. water changes take care of it. of course if people don't like doing changes, that's an issue. the only "dosing" i do is add calcium crystals (1/4 cup) every 2 weeks to a water change. my coralline algae goes through it like crazy. cool vid man.

any reason you haven't switched to a calcium reactor? seems it would be the more stable solution to avoid these types of situations plus the trace elements would be a extra bonus... Nice vid man just proves how testing is crucial for success
Klem Reefing
Klem Reefing - 3 years ago
Haha, I think you picked up on my growing distaste for two part dosing.! And although a calcium reactor isnt without its frustrations as well, I agree with you in that it seems like more of a long term/stable piece of equipment. My problem is that the one Id like, Super Reef Octopus CR3000D, is 550.00! Then there is the digital CO2 valve thats 300.00, plus the co2 tank, ph probe, and hoses.... I think Im looking at a grand to make the switch. Its a hard number to justify right? uhhhhhhh. But that is where im going as a long term reefer guy. Is there ever a point when the tank just runs and we dont have to sock money into it? LOL Happy Reefing man!

Here is a tip I use for the tubes going in the jugs: buy 1/4" acrylic tube from BRS and cut a 10" piece or so to add to end of tube going into jug. This will eliminate the hose curling and keep it on bottom of container.

ReefSpy
ReefSpy - 3 years ago
jahhoeva I think those connectors work better for positive pressure (water pushed in) and not as good for negative pressure (water sucked through). I'm guessing the seal has potential to allow air in under negative pressure. At least that was my theory.
jahhoeva
jahhoeva - 3 years ago
I will keep that in mind. Thanks for the tip!
ReefSpy
ReefSpy - 3 years ago
jahhoeva cool. Glad to see I wasn't alone. Same thing with me. Keep an eye on it. One of my lines stopped pulling fluid and my params got out of whack till I noticed what was happening. I got rid of that murloc and just put rod straight to tube and never had issue again.
jahhoeva
jahhoeva - 3 years ago
When priming my dosing pump to fill the lines, one of them would not prime (manually running pump to fill the lines). I played with the rod and fitting for a bit and got it to prime. So far so good. I monitor the lines from the jug to the doser for air, but both tubes have remained full of fluid with no air gaps.
ReefSpy
ReefSpy - 3 years ago
jahhoeva did you ever have a problem with those murlocs not keeping a seal? Mine worked great at first but after a few months they stopped allowing suction through the lines and i was just pulling air. Replaced and same thing eventually happened again.

I built the jugs BRS showed with the bulkhead in the cap and rod into the jug. Works awesome.
