    • Maintains temperature well
Pattern Name: 25W
Works really well, almost too well. Very quiet, but has a little light on it that can bother you overnight if you're really sensitive to light when you're sleeping like I am. It works really well at getting to temperature and maintaining that temperature, however if you have fish that are particularly temperature sensitive, make sure to check the temperature regularly, just stick your finger in it and see if it seems too warm. I set up the tank and this heater a little while before getting a fish so that it could get up to temp and I noticed that it got a little warmer than expected and turned it off. It comes with a little sticker thermometer, but it doesn't give an exact temperature, it gives a range of temperatures and ones it goes above a certain temperature, it won't display it if it goes below that temp, so I recommend getting a thermometer if you're feeling particularly nervous about it, but overall it's a really good product and I really like it. It gets up to temp in a good time and maintains that temp well ... show more

    • 500W big enough for 55 gallon
Pattern Name: 500W
Review Image by Derrik Derrik
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

    • Fixed Temperature Control
Pattern Name: 100W
Review Image by Leon Office Leon Office
Review Image by Leon Office Leon Office
I purchased this heater as a replacement since my last heater finally gave out. The heater itself does its job, it heats the water to temp and keeps it somewhat to where it’s set. It was a great addition having the temp probe and digital readout. I have tested it against another heater’s internal control and mercury thermometer and it seems to be mostly accurate. My only issue, and reason for giving this thermometer a four star review, is because the temperature dial on the top of the heater, are the ONLY temperatures you may choose to heat your aquarium. It is not variable, or adjustable. I found if I set the heater to 75, the tank would sit around 72, and if set to 79, it will stay at 79. The seven degree swing seemed rather large IMO. Like I said, the temp is not variable, and if the selector on the heater is not lined up with a number, the heater will not turn on at all or heat the aquarium. All in all it does its job, but if you want variability when selecting a temperature, spend a little extra money and buy a heater with that option. ... show more

    • Great heater that takes up minimal space in the aquarium
Pattern Name: 300W
I would recommend this heater to anyone that is looking for a great product. It takes up minimal space in the aquarium, is easily hidden behind live or artificial plants, is easily adjusted with the turn of the knob and the digital readout is easily seen so you can monitor the temperature. I will definitely buy this product again ... show more
