Thanks for looking.

My sumpless 77 gallon evaporates about a gallon a day. I use a glass wine carboy that holds about 7 gals. as an ATO reservoir & it lasts close to 7 days (lucky 7!). That's under LED lighting. Depending on how much heat your lighting adds & additional water movement with sump, YMMV, but I'd guess 9 gallons will easily last a week.
