32 Biocube Question


New Member
Hey y’all. Shopping for my next tank. How often do you need to fill the auto top off on your 32 Biocube? Just wondering how long I can go away for a day or 2 with this setup.

It all depends on your salinity if your salinity is higher then 1.026 top it off. A day or 2 won’t hurt I definitely wouldn’t leave it alone for a week though

It depends on the relative humidity around the tank. If you run air conditioning for example, the humidity will be low and water will evaporate faster. As a rough estimate I'd plan on about a gallon every other day.
