Yikes. I it's costing me about 65.00 a month to run my aquariums. I have
a
55 gallon tank, a 10 gallon turtle tank and a small 3 gallon acrylic tank.
Does anyone else have this problem? Apparently the tank heaters are very
costly to run. And I have 3.

Not sure what the exchange rate is, but my 9 tank system in the garage is
run by 4x 300w heaters, a 6 tank system by 1x 300w, Oase pump for
circulation at 38w, powerhead for smaller system at 50w, 1x 300w in a 48" in
the house, plus running costs for the house = approx £50 (GBP) per month.
