Review: Very good heater for your smaller fish tanks 👍🏻 - 4th heater I’ve tried, this one is by far the best, keeps a very steady temperature. Very pleased with it, would definitely recommend it for your smaller tanks 👍🏻
Review: Good value intelligent heater - UPDATE: Oct 2013 Still think this is a great product. No problems at all. Easy too keep clean. Still looks like new. Currently checking with FLUVAL as I have been told this range has an auto shut off if you forget to turn the heater off when draining the tank ( does not say this on their site though). I will post another update once I have had feedback from Fluval. Original review This is a great little heater keeps the water temp very stable. I have a digital thermometer probe in the tank 2 as a double check for even heat. I bought this heater after I broke my original and very basic heater by doing a 25% water change without letting it cool down or switching it off! Not even this heater will stand up to that, however the cage surrounding the heater tube would catch any glass should you make the same mistake, though its primary function is to avoid cooking you fish from close contact. The colour change backlit LCD screen is very handy and easy to ready. Red - too hot / Green - just right / blue - too cold, plus water temp in Centigrade or Fahrenheit. Adjusting the temperate is very easy in situ as well, with a simple and sturdy lever at the top of the unit. Theoretically you could get ride of your thermometer to make your tank more aesthetically pleasing through less clutter. (but best to have non electrical backup thermometer IMO in case of power cuts) The unit samples the water directly, rather its own internal temperate, to give accurate readings. Other features are: 1) to be able to detect low water circulation around the unit to avoid hot and cold spots and displays a flashing screen with LF for low flow if detected. This works well e.g. if you place the heater too near a side, vegetation or the bottom.. 2) flashing warning if external factors raise or lower the tank temp by 3 degrees or more. The unit also comes with two fixing bracket options to allow you to back mount in your tank and and an angled bracket for corner fixing. The suckers are very strong and also adjustable so you can more accurately raise or lower the height of the unit in your tank All in all a well thought out and well made heater.
