Storing mixed water.

[RareZ]

Hi all, I dont remember whrere I read it but somewhere I saw that if you keep ro/di water for a long time it's said that carbon dioxide gets saturated into the water because there was a lack of that present during the RO/DI creation. And it said the water should be sealed and used as quickly as possible (after mixing whatever you need that is).

I have no idea how much of that is the truth and I really cant recall where I've seen it. So dont hold me to it, I am just throwing it out there as this thread was about storing ro water.

Can someonetell me what a brute is? Appreciate it. I need to find a good option for a small NYC apartment also.

What they didn't tell you when showing you the pics of a Brute can is the reason for it's use...it is considered a 'food-safe' can. Lesser quality cans can leech some sort of chemical (anyone know for sure what it is?) into your stored water and that's what makes them unacceptable.

Did you ever notice the 'slime' in your storage container after you stored water in there for awhile?

The reason for the powerhead is to aerate the water..and keep it that way until you put it in your tank.
Since we do not run air pumps on SW tanks, we depend upon our skimmers and water movement to keep our water aerated. The addition of aerated water during the water change would seem to be rather important IMO.

My RO/DI just sits in a brute container (i usually have about a week's worth).

my saltwater is always circulating with a pump (and heated before i'm ready to use it)

Right now I'll make up 5g RO/DI water in the evening (usually right after a w/c), add a pump, heater and salt, and let it go for a day. I'll check the s.g., and if all looks good, cover it and store it.
The day before the next w/c, I take it out, add the pump and heater, run it overnight to assure aeration (I also use the venturi tube as a just because) recheck s.g. before using and go ahead with the change and repeat the cycle. I can certainly understand that if someone has a big tank, and makes large changes, letting it run continuously makes sense for those volumes, but as I rarely would ever need more than 5g, is it reasonable to let it sit the way I do? I felt that as long as I sufficiently aerated it before use, I would be fine. Any thoughts?

I agree with Henry. I've never had an issue with doing it this way.

Ro/di

I make 5-8 gallons of RO/DI and save them in the drinkable water gallons they sell at the supermarkets. So thats about 5 or 8 containers seal it and keep it in my closet.

Once I'm ready to do my water change a day before I place it in a bin and add the salt and what ever other changes I need. Add a heater and a pump and leave it over night. The next morning I make the water change.
