Ive been struggling to keep my tank temp down, Im on octopets waiting list for a bimac, and Ive been coming home to 83-85 degree water.

What is best, safe, and deadly as far as temperature is concerned?

Does anyone have ideas on chilling?

I currently have a fan in the canopy, and a 6" clip on blowing on the sump. I think the dolphin pump is just too much heat for a apx 60-70g system....

thanks

I would suspect your pump, but then the temperature you keep your house matters, too.

I was able to lower the tank temperature in the summer to about 74 degrees by keeping the house at a lower temperature (70, I think), especially at night so the tank had time to get cool. Also, putting a 5 inch fan blowing on the sump helped.

Another source of heat might be your lights - an octo can get by with a fluorescent, does not need high temperature lights.

The tank temperature you have now is too hot for a bimac to live in - it's not really a tropical octopus.

If your water is that hot, you definitely have a pump or something that is running waaaaay to high...try a Rio or other brand of magnetic drive.

Bimacs are not only not tropical, they are barely temporate. You should aim for temperatures under 70. Lighting is not critical. Ambient will do.
