Making Lemonade - Mike's Lagoon


Well the tank isn't particularly shallow, I mean ok the water level is maybe 22" so a bit short for a tank this size, the surface area is most likely the culprit. As to an estimate? eh.. it's going to vary based on temp/ambient humidity (due to weather and tank) etc... but I wouldn't be surprised if 20 gallons is the answer to that, it may be lower I haven't exactly paid attention to how often I fill up my RO tub, and to be honest during this time the days do seem to all merge together.
20 gallons isn't bad for a tank of that size!
