Have had my 4ft tank setup now for about a month and the temp stays around 32 degress, This a little to high for my liking. I looked under the hood and noticed it had 2 Sylvania aquastar f36w, 10000k marine lights in it. Am i able to use these for a freshwater tank or are these what could be causing the high temp in my tank. (it is not the heater, took it out). Any help would be appreciated.
All you have to do is get different light bulbs. It looks like you have a Actinic light bulb, hence the blue tint. Actinic is used in saltwater tanks. When you get different light bulbs get colormax and daylight bulbs.
