Damn heat....

Feb 18, 2005
If you use powerheads, they can add 3-4 degrees to the tank depending on water volume and brand of pump. Since its been warmer lately, Ive put one of my powerheads used mainly for flow on a timer. It goes on for 20 minutes every 2 hours. The tank temperature went down 4 degrees.. =)

Does anyone know of a good semi-inexpenisve powerhead that is known for low heat?? Id love the ones that actually has its motor on the outside of the tank and is attached to the propeller with magnets, but those are way expensive.
