I'm having some trouble with my 12 gallon nanocube. I can't seem to get the temp regulated. First the tank was to warm, tracked that down to a powerhead, so since there is no corals in the tank right now I turned that off. I am going to be buying a chiller before I put anything else in the tank, since I am also going to upgrade to MH lighting. So now the powerhead is unplugged, and the temp is around 75. So I went and bought a heater for the tank. I put the heater in compartment number 2. Now no matter where I put the thermostat on the heater the tank is only getting to 76. It seems as if there is no flow going through the back area. There are not a bunch of different levels as I have heard people talking about. Maybe at the most there is two different levels of water put that is it. I am not running a high water level at all, you can see the top of the water outside the tank meaning the level is under the black trim. Any help would be appreciated.
