Does anyone else have a problem with the water level dropping after like a week? i gots a 30 gal and it drops like almost an inch a week. it is next to a window but its a north facing window where the sunlight never beats on it. I did just upgrade to a heat lamp instead of a uvb lamp due the wininter season coming up and did just get a water heater but its been doing it before them.
Anyone else have this prob?
