I have read you shouldn't put lights inside the tank. However, if I do not place the lights in the tank and cover with slate top I can't get my tank temperature above 90 degrees Fahrenheit due to the draft in my apartment (and the draft is not going to get fixed. I've spent money on several different lamps (I now own 6 different types) in attempt to use the lamps above the tank on my screen covering. I am a college student so I'd like to not spend hundreds of dollars on lamps considering I've already spent so much. I want what is best for my little guy, so I was wondering if anyone had any suggestions.
