![]() Why wouldn't it last (theoretically) indefinitely? Either bottled and capped or mixing and heated?

![]() If it was airtight I'm sure it would be fine. However when there is a bit of air exchange it seems to put an expiration on it. If you don't have enough flow to keep it mixed to get what I call Skank Water....its nasty.

![]() Unless its completely sterile it will develop a bacterial biofilm in it on the containers surface and those bacteria may produce unwanted bioproducts (ie. your RODI water isn't as pure as it once was).

![]() What if you fill up one of those garbage bins with RO water only? Would that be sterile enough sitting for a week or so? Then he can add salt in a seperate mixing container a day before he wants to do a water change.

![]() I would imagine it wouldn't be a problem letting the water sit for a week, lots of people do it. I wouldn't let the water sit stagnant though. I'm not sure what the bacterial growth rate is for a week. I usually make up water the day before I need it. I have found that if I let water sit in the container for too long (especially repeatedly, say make up water let it sit, then refill the containter immediately) I can wipe out a goodly amount of brown stuff off of the side of the container after I empty it.

![]() I mix 25 gallon batches of salt H20 whenever I do a water change. I use rodi water, then throw a maxijet in the bottom of the "garbage can" (which is actually a white, food-safe container with handles and lid from a wine making store).
I've leave the water stirring for a day or two before putting it in the tank in two batches (one day after the other). I wouldn't leave 'fresh' salt water to sit for more than a week -- at the most. Speaking just personally, what's the point of ro/di water if we let it degrade before using it? Erik NB: for my water topoff water (also rodi in a 5gallon foodsafe bucket) I leave an air bubbler in the base of it to provide some water circulation. This water lasts about a week as well. |

![]() The only thing I think I have to add, is that if I leave water sitting around for awhile I also like to add an airstone in addition to the pump
