How long do you think that water should mix before you put it in your tank? I've been told at least 4 hours, but I want to make sure. I always do it overnight, but my tank's really low on water and I want to add 2-3 gallons today cuz the pump on my filter is starting to run dry. Rather than shifting stuff around, I'd like to get some water in there asap.
