Im getting two new jagers for my 120g and i was thinking 2 300 watts? It gets pretty cold and my hydor 400 is a pos and when its set at 80 it stays ay 72 and wont change the temp. Wouldnt this make the electric bill better? As in it would heat up for shorter times? Would 2 300 watts be too much? Im looking to keep it at 78 and the room temp is about 64 or so in the winter.
