I have a 200W heater on one end of my tank it seems to keep that end at the correct temperature but the other end seems cold can I add a 50w heater to the cold end to help regulate the temperature?
Strip thermometers are not very accurate you have that right. Secondly before you buy another heater get an accurate thermometer and find out your temperature.I wondered about this. I have a 55 gallon tank. The heater is set at "84" degrees and next to the filter. The other end is 77-78 degrees. Should I consider another heater on the other end?
Also I'm getting a more accurate theometer for the tank. Currently I have the sticker one that is placed outside of the tank. Where is the best place to place that? In the middle of the tank? What about if I got two heaters?
