Nick Jarrett

The waste water is just the tap water with a higher tds, perfectly safe. I mean if your tds is 200 and it bumps it to the 250 then it's still below my 440!

Jcee's Corner - 3 years ago
Nice video.... Drinking DI water as you know is arguably not a good idea. DI water great for "Reef Usage". BulkReefSupply told me for drinking water they suggest their RO system which does not have the DI filter because the DI filter removes too much and might not be good to drink water with no minerals. It almost like distilled water being super "clean" and arguably some say it may not be healthy over time to drink DI or distilled water. Thanks for a great video and the ideas on how to save $$$ for your "fish tank" using the DI etc.
Aquascape Dreaming
Aquascape Dreaming - 3 years ago
Jcee's Corner this is actually nonsense. You get all the minerals you need through organic vegetables and meat. Drinking purified water cannot harm you as you are simply hydrating your body. I read a very interesting article on this very thing. I'll try to find the link again if you're interested.

You can buy pumps to pump the waste water back in so its about 1:1 waste or use a distiller which wastes none but uses a lot of electric

how long does it take to fill a 5 gallon? also can I hook it up to a kitchen sink?
Nick Jarrett
Nick Jarrett - 2 years ago
Well 50gpd (gallons per day) would be 2.4hrs, 1.2hr for 100gpd and with decent water and clean filters you'd waste about 4x (or use it on the plants)

I have a 13.5 gallon tank, I'm definitely doing this hobby on a budget, I'm not asking for trouble but I don't think that an RODI system is necessary for such a small, simple tank, what are some other (less expensive) ways to get salt water for water changes?

Did I hear you say 50 ppm coming out of the unit before the DI stage? If that's what it is then your membrane is shot. TDS should be less 10 or less before it reaches the DI.

I don't think RO/DI water has a limit on that. It could be stored for as long as you need without a problem as long as it is out of direct sunlight.

CoralFish12g
CoralFish12g - 4 years ago
If you mean't flushing, all you have to do is disconnect the DI canister from the rest of the unit and let it run for a few minutes in the beginning before you make your water. This protects and keeps your DI resin cleaner once you reconnect them.

I have one more question about the unit I got one and am waiting for it to come in, but I was curious when u turn your hose off and are done with everything, what do u you do with the water in  all the champers, do u dump them out or just let them sit in there to the next water change?
CoralFish12g
CoralFish12g - 4 years ago
I just let them sit there. I don't think it hurts anything.

this may be a stupid question but what's the difference between a rodi unit vs a ro unit?

One makes a RO water and the other makes RODI water. The difference between the two can be learned in this video of mine: https://www.youtube.com/watch?v=rDdcqGxDLN4

Great video. During normal operation, when you are done with filling do you let the unit and filters dry or do you keep it wet some how? I guess my question is about storage between uses.

Thanks!
CoralFish12g
CoralFish12g - 4 years ago
I don't do anything to them. I just leave them and I'm sure they dry on their own, but they might be still wet from the last time depending on how often you use it. I don't think that matters

shifty51008
shifty51008 - 4 years ago
+Jayden D_Thang you use the rodi water for the base water, then add your salt mix to the rodi water till you reach 35ppt or 1.026sg using a properly calibrated refractometer or hydrometer.

Giorgos Tsagos
Giorgos Tsagos - 5 years ago
I dont understand why is bad to drink the water after it passes through the DI unit. Its just plain water with nothing in it!
All I know is we shouldn't drink JUST that and nothing else because we need the minerals that there are in any other water source. Anyone willing to explain to me where I'm wrong?
Uhohhotdog Gaming
Uhohhotdog Gaming - 3 years ago
shifty51008 yes it's bad because the pure water will absorb nutrients from your body as it passes through
shifty51008
shifty51008 - 4 years ago
+Giorgos Tsagos it's not bad no matter what you read, you will get all the minerals you need from any food you eat or anything else you drink, but imo rodi water tastes like crap anyway
Jeramie Scott
Jeramie Scott - 5 years ago
+Giorgos Tsagos Just google why its bad to drink distilled water, RO/Di water is the same thing.
CoralFish12g
CoralFish12g - 5 years ago
+Giorgos Tsagos Yeah, it is confusing, but apparently too much of the water without all those minerals is bad for you. I don't think if you drink a glass of it, it will be that bad. It is only if you drink that consistently more than regular water that it is harmful.

CoralFish12g
CoralFish12g - 6 years ago
Hi Olu, No, the black does not go through the di so it would seem safe BUT, you have to remember that is the waste water from the ro so the ideal drinking water would come from the blue tube but before going into the di. I hope that makes sense.

multisturge
multisturge - 6 years ago
Another great thing about making your own water rather than buying it from your LFS when it comes to money, think how often you end up coming out of the LFS with a load of other stuff when really you only said you was only going in to get the water. I'm saving up for a RODI system from Osmotics (think they might just be an UK company) but they really been helpful and forum sites too as I been put off by getting a unit because one video I saw was using a drill and installing a tap but I see how simple it really is. Thanks to osmotics' and reefer's support on forum sites I can make my unit portable (don't have an outdoor tap) by connecting it to my electric shower which would keep the pressure gauge reading up in theory. On average how long does it take to feel up the container with RODI water?
multisturge
multisturge - 6 years ago
forgot to mention in the UK I pay £2.50 for 25litres of normal RO water with around 15ppm TDS and for not having a car I have to plan in advance with my parents to take me to my LFS to buy the refills, before my last refill I had a week of no RO water after my last water change until my refill so if my tank crashed from a spike during that week I would of had no water to fix the disaster as my LFS closes by the time my parents finish work.

TheFishTank Doc.
TheFishTank Doc. - 6 years ago
Nice vid!!!.
It is the R.O.membrain that does all the work not the DI stage. The R.O membrane should reject 98% of all the T.D.S. The DI stage only takes otut the last remaining 2/3ppm, mostly made up of heavy metals (copper, zink, alluminum ect...). Your BRITA water filter will not have an R.O membrain in it. It will only have carbon filters remove chlorine, and bad tates. The carbon filters on your R.O.D.I  filter are only there to protect the R.O.membrane, and make it last. The water going into the R.O membrane will be about 50ppm. It should be 1 to 3 ppm coming out.

+multisturge Yes, these are all good. I do use it now on tea and watering
multisturge
multisturge - 6 years ago
yeah the waste water is very good to water the garden and any other plants you have around/in the house. RODI water has other uses too which helps your parents/partner be more happy to having the system in the hose especially if you're going to take up some space under the sink (except less trips to LFS). Can use it to clean the windows and tank glass, good to make tea (I'm in UK with hard water so my kettle gets covered in limescale) and baby formula if you have a baby, can also be used to fill up your car radiator.
