i have a rena cal 200W running in my 65G hex tank. I have it set at the minimum temp of 66F and my tank water is at a constant 82F...what gives? My ambient room temp is 78F. I dont believe that 200W is too much for my 65G tank...am I wrong?

Thanks.

i have no lights at this time. this an unplanted tank that im getting ready for plants. like i said, the heater is set at 66F and my water is 82F (a couple degrees higher than ambient temp). i tried bumping the heater setting up to 75 the other day and my tank just got hotter, approaching upper 80's. I am thinking that the heater is defective...it is atleast 5 years old.

in the winter the house goes down to 68 at night and about 70-71 during the day. i should use the heater then, right? I mean, for my tropical fish...they probably dont like it that cold. id probably keep it around 78F preferably.

i know for a fact that the heater keeps coming on. it has a light when its on and the light is off when it is not heating. even though the water is at 82F it keeps coming on...faulty heater i believe and i will replace it. thanks diana.
