in an effort to cut heating costs I have deployed 3 x 250 watt metal halides over my tank. This approach seems to work well as my 3 x 300 watt heaters only seem to kick in for a few hours during the late night hours.
That's fine in the winter but how high does your temp get in mid summer without a chiller?
