Outstanding heater. The included thermostat is very accurate, tank heated up slowly over a day. The fish are loving the 77.3 temp... The Heater is of good quality and should last a long time...

  • Awesome design!
Pattern Name: 150W
These heaters are FANTASTIC! Most heaters are normally a few degrees lower than what they are set at but these actually run a degree or 2 hotter which is GREAT! The compact design but high wattage output is great for smaller tanks! Most of your small/compact heaters are preset and dont normally get to that temp. These have given me no problem at all in the few months I have had them and used them. As an added bonus the thermometers that are included are great for our axolotls while they are being tubbed! 10/10 Will be buying again! ... show more

  • 500W big enough for 55 gallon
Pattern Name: 500W
I originally bought a 300W aquarium heater for my 55 gallon aquarium. (A different brand) It said it was good from 40-55 gallons. I installed it and "maxed it out" at 89 degrees, but my aquarium would only get to 66.5 degrees on the other side of the aquarium opposite the heater. This was simply too chilly for my fishies. (I have a freshwater tropical set up with mostly Tetras) I sized up to the Orlushy 500w which was substantially larger in size compared to the 300W heater and I now have no problem heating my aquarium into the 80's if need be. I believe this one advertises that it will heat from 50-80 gallon. Learn from my mistake and go with the 500W heater if you have a 55 gallon or larger to get proper heating. Orlushy was the only one (I saw) that provided the larger sized 500W heater. Price was great and product looks good in the aquarium. I don't think my fish would have made it through the cold winter with out it. Because of the ridiculous cost of (even freshwater tropical fish) now a days... you don't want to chance them all dying for something that doesn't cost that much! In my opinion. Hope this helps! ... show more

  • Not for 3gal or less!
Pattern Name: 25W
This heater works great! I purchased the 25w for my 3 gal quarantine tank and I cannot get it below 80’. This heater does NOT adjust! So, unless you have fish that need 80’ in a tank or have a 3 gal or less, then don’t get it!
