I just ordered a male pastel and Im getting my tank ready before it arrives. I have a 10 gallon tank and I cant decide where I should put my under tank heater. I have repti bark and the heater seems like it would warm the tank better if it were put on the side of the tank since the heat wouldnt flow as good through the bark. What do you guys think would be the best way to have the heat pad set up? Thanks in advance
