   The specifications don’t mention the tank size this heater is suitable for, but it fits my 5 gallon tank perfectly. Easy to adjust the temperature. Been using it for about four weeks now, works perfectly. My fish are very happy.

   Won’t go any higher than 81*F, March 26 2014

   This heater is ok. I bought it for my 3 gallon and I am disappointed that it doesn’t matter what setting I have it on. I cranked the dial to max, but it still cannot heat my tank any higher than 81*F. I’ve been wanting my tank at 83*F. I have my tank near a window so maybe I need a stronger heater for the winter months. Otherwise, it works well at maintaining a constant temperature. I wish it would go higher though. I should have gotten the 50 watt.

   It works great. I was looking for a short water heater and this does the job wonderfully. Great price also
