sup guyz, i am just wondering how long can we storage RO water in a container with out any powerhead. just RO water. thanks man

[drperetz]

As long as u want??

Is it a closed container?

I would throw a cheap maxijet in there to create some surface agitation. Keeps it oxygenated. Also keep it covered. Dust settling in there will add impurities to the water.

Hey R,
Question...
If i have a 5 gallon jug (with a cap), of rodi water stored for a while, isn't the only thing gonna change is the pH level?

	RODI High quality filtration systems used to purify tap water before it is mixed with salt or added to the aquarium for evaporative top off. Most municipal water supplies contain unacceptable levels of Nitrate, Phosphate, Lead, Chlorine, Copper etc. It is critical that these impurities are removed as some are toxic to reef organisms and others fuel algal blooms that can quickly overtake a reef display. Again, there are many brands and many configurations to fit most applications.

If you're bucket is capped, and you have a powerhead in there, I wouldn't worry about variations much.

Its a poland spring 5 gallon jug..

cant put a PH in there.

Just make sure you cap the container or bottle.
Leaving it open may allow the introduction of undesired particles.

I wouldn't be too concerned with adding a powerhead.
If its closed, what exchange can occur besides temp.

I store my Rodi in a 20g brute; taking approx 5g every 3 days to refill my tank reservoir.
