R.I.P.
I think If your trying to evap that much water a day, room temperature, humidity has a big impact on how much is being evaporated. With an open hood & higher lights I think normally you won't have issues with fans, you can steady your temps. If you need more evaporation then a dehumidifier, A/C or chiller would be required to get better, IMO.
I should have a pretty good evaporation rate. right now I have around 8sqft of open surface area on the tank. The new tank will have half the volume and about 19 square ft of surface area.
