How long can you keep RO?

Another question! How long until RO turns bad without a power head for circulation?

until it gets contaminated with something.

RO/DI is pretty much pure water its not going to grow much on its own or go bad unless something gets introduced into it.

I keep mine in a 250 gallon vat as salt water with circulation and heat. Never a problem.

Theoretically, as long as it is covered, and doesn't get foreign matter introduced, it should keep indefinately (well, except for evaporation)

I keep my RODI in a closed big bucket without aeration. IÂ´ve never had problem.

Keep it covered and in cool, dark place.

Also, don't keep 55 gallons if you only need 5 gallons at a time.

The more turnover you have the better it will be. If you use one gallon a day you'll be replacing 20% every day so it will stay "fresher".

You can keep RO for evers and evers.
