Hi. I have a 45 gallon tank. In it I have a 200 watt top fin heater. Just below the top thermostat part it has a line that says that it should be lined up with the top of the water, so that is where I have it. I noticed my tank was up to 84 degrees. Eek! Scary! It doesn't seem to be bothering my fish, but it doesn't seem okay. I turned it down to low. It only has a dial with a few marks on it from high to low. No temperatures. Now my tank is at 86! I unplugged the heater and opened the lid on the tank and it still hasn't cooled down enough. It appears the heater just comes on for a while and shuts off for a while like it is on a timer. Does anyone know if it is actually reading the temp? Should I get a new heater? What is a good/inexpensive heater to buy? Please help! Thanks!
