Ok so summer is coming and I am going to need to run a fan to keep my tank cool. The other day may tank temp went up to 80.5 so I turned the fan on over night and tank temp dropped to 75. I forgot my heaters were unplugged cause tank usually rans at 77 without them. So now I want something to control the heater to keep my tank at 78 and something to control the fans if the temp goes over 78.
I have looked on line and found the ranco 2 channel controller. Anyone use one of these?
