Stagnant Water

[Hotrod32487]

If i were to de-chloranize some water and it sat for a few days in a regular drinking glass, would it still be ok to add to my nano tank as top-off water? By then it would surely be stagnant and i want to know if that would be a problem

Don't do it. Better off going to the windmill and getting their RO\DI water @ 20cents per gallon. Tap water has to many disolved solids that can give you an algae bloom.

That would be my main concern in such a small tank. That the excess TDS would quickly add up each time you top up.

Any bottled drinking water will work just as well. They have all been filtered to a consistent quality.

Avoid the distilled water and the spring water. Filtered drinking waters are very close to what we create with RO/DI.

Why avoid distilled water?

Ok so say i get some RO/DI water from a store, do i need to worry about it going stagnant? Would a lid being on top of the bottle help?

RO/DI water from a fish store will be good. I'm not sure where else you would find deinonized water. Keep it under a lid to keep dust and other pollutants from getting into and don't worry about it going stagnant.

You can also use the RO water from the vending machines you find in front of HEB, WalMart, and I don't know where all else. It's not deionized, but it's much much better than tap water, and cheap.

The water won't get 'stagnant' unless stuff gets into it. Keep it in clean containers and covered. Storing it in sunlight probably wouldn't do it any good though.

Why avoid distilled water?

It is more expensive, for one. I don't think it will hurt anything but the distillation process removes EVERYTHING from the water.

I think there is another reason but I can't remember.

distillation process removes EVERYTHING from the water.

Isn't that the goal of using a RO/DI unit?



It is more expensive

You are right about that but I still use it for my nano with no ill effects and its been running for 1.5yrs.

:unsure

[MattK]

Oxygenation maybe? or lack there of?

Here is my guess R/O water removes almost everything except minerals which is what the human body and other living organisms need to survive. DI removes even the minerals. It' kind of like the question which will make a nail rust faster RO water or saltwater? Answer R/O, my kids science fair project
