I was wondering what people thought it costs to run their tanks. My latest bill was like 130, but there are three of us that live here in a large 3 br townhouse. We all have plasma tvs that get left on when they should be turned off and waste electricity one way or another. Also, I have a waterbed that is kept at 92 for the winter. I don't have any special lghting and only leave them on for 8 hours a day. And all the tanks are heated. All things considdered, I don't think it's that bad. I voluntarily pay an extra $30 for electric for my tanks. The other two are happy wth this, but is that really a fair deal?
