I’m having a hard time keeping the temp and humidity at constant levels. I have a 40 gallon glass aquarium that measures 36x18x16, Eco Earth substrate, back and sides covered, 40 gallon size UTH. As of now I’m using a light to maintain temps. The top is covered with a hinged screen, I have the open area around the light covered with plexiglass. My question is, will using a RHP maintain my ambient temp and not kill my humidity levels like the light?
