Biocube ATO

[CavalierReef]

Greetings all. Just set up my 32 gallon Biocube and am trying to decide on the size reservoir I need for my ATO. Can some one using an ATO on their Biocube (with lid in place) let me know how much evaporation I can expect? Thanks in advance.

I have a BioCube 16 with no lid. I go through 5 gallons every 2 weeks. I figure you’ll go through way less with the tank sealed.
