Evaporation

[Magickiwi]

Right now my open top 90g is using just under 2.5g/day of ATO. Sometimes less sometimes more. Right now is has been so dry in my house that it's on the upper end for evaporation. In the summer I was going through about 5g/week.

Another one that says that is about normal, especially in the winter time with lower humidity levels. The winter I go through 5 gals every 2-3 days, in the summer it is every 3-4 days..
