How much water evaporates from your tank?

80 gallon rimless 40 gallon sump 2 1/2 gallons a day

About 15 gallons a week in 108 rimless and 40 gallon diy sump. Part of the sump holds 8-9 gallons of top off water. I would say about 125 gallons total water.

I've got a 500 gallon system. It was around 11 gallons a day, but I was having heat issues, so I added some fans that blow across the water. It's about 13-15 gallons a day now.

90 gallon display, 20 gallon in 25 gallon volume sump.
1gallon a day now. This tank is a upgrade from my 46 bow that had a 10 gallon sump that held about 5 gallon s of water, it to used a gallon a day in summer. I'm curious to see how much it will evaporate during summer. I have terrible well water where I live so I purchase all my R/O its a ##/)(&$ carrying multiple 5 gallon containers of water all the time, especially with bad knees. But my love for this hobby, and it's addiction are still winning out, even over the pain of lugging heavy water containers......
I know....bla....bla...bla. Just kidding.
