I just bought an Eclipse System 3 Aquarium. I am having trouble with it
~overheating. Thinking it was the lighting (6W NO haha), I left the
lighting off for a day (I don't have fish yet). The temperature did not
decline. In fact, it went up - from 81F to 83F. I am now quite certain
that the motor in the filter (35GPH) is heating it to this temperature. It
doesn't seem to me that such a small motor could do such a thing. Is this
normal? Has anyone else experienced this?

Thanks,
Martin
