I brought one of those Hagen Tronic 200 W heaters for my 55 gallon tank, andit's coming on and keeping the tank at a steady 80, but I've seen some condensation on the inside of the glass. 8O What does it mean? Is it cracked somewhere? (I haven't seen any). Should I scrap it all together and get a new heater.....again? HELP!
