Yeah, that was a REALLY bad guess lol I'd say it's probably closer to .75 to 1 gallon a day simply based on all the info you guys have given lol
It depends on your home (level of humidity) and how much surface area your tank/sump has exposed to the air. So what is true for one tank isn't necessarily true for another. Size of the aquarium doesn't matter as much as exposed water surface area does.
