I have a 12 gallon nano that has started to develop heat issues. Tank is holding steady at 78 degrees BUT the heater never turns on with my temp controller because the heat created by the 4 pumps inside, two MJ 1200 for skimmer and return, along with to hydor 850 power heads. I installed a screen instead of having a glass top to try and cool it down. Didn't do much. Guessing my Remora-S is cooling seeing it's external with lots of water flow. I currently have an old aerator pump outside (temp has been below 60 degrees here and I though injecting cold air might help, but it's not really. I just set my wavemaker to alternate every 30 minutes to reduce pumps running. I have a woodstove which will be utilzed in the near future with cold weather approaching. I would guess it will greatly increase the temp of the tank. I was debating the CSXC-1 or the JBJ Mini-Artica?
