Just curious.....how long do you allow your ro/di water to sit before you mix it up with the salt? The reason I ask is that I've just gotten my 20 gallons of ro/di water and something came up and I won't be able to do my water change for a couple more days. Is it ok to leave in the storage containers (those 5 gallon plastic containers) for a couple of days before I mix it with the salt?
Thanks!
