well you see, i dont have my own ro unit yet, so i was just going to get my buddy to bring over his and fill my tank up, should last me long enough till i can go get my own

If you have 150g of RO water, I would put a large powerhead in it to keep it from going stagnant. Also, I would keep a glass or other top on it, but do not fully enclose it.

Why's that?

I consider water to be a form of food. Isn't the best way to store food in a cool sealed container? If bacteria need O2 to live, then keeping water in a sealed, unariated container should last longer, No?

Danny,

I don't exactly know why I would do that, but I would. We're not talking drinking water here, we're talking about RO water that will eventually to into someone's reef. What kind of bacteria are going to get in there? What will they live on? Inquiring minds want to know :smile:

I don't know, nitrifying bacteria could somehow get in there over time and start the cycle. Anything really, crypto sparidium? :razz: I just figured that anything to be stored should be sealed and chilled (cool area) to extend it's shelf life. Oxegenating the water can wait until the salt is mixed in later. Some people mix their water then store it which is a very bad idea for obvious reasons IMO. Even heating it would speed up the bacterial metabolic rate so I don't see the point.

Truthfully, I'm not basing this on any proven scientific evidence, this is just my logic at work here. :lol:

Here's an extensive page on Cryptosporidium:

Well, now I don't know what I would do with 150g of RO water :eek:

well today i plumbed my ro water tank, and am letting the ro unit fill er up right now, i got a small powerhead in there right now, and i'm hoping everything going to go all good, lol
