Fluval M Heater Review

by Kmuda

Overview:

Finding a good heater is becoming more and more difficult these days and having historically had such good luck with Fluval Tronic Heaters, I decided to try Fluval's latest heater, the Fluval M.

It was a mistake.

Ignore the "Reflective Technology" marketing hype. It's a bad simulation of a mirror. It does not hide in the background at all. But that is not the real problem. My heater only lasted about 3 months in 55 gallon tank containing nothing but a Pleco. It will still heat the water, but cracks are clearly visible in the glass, so it has been removed and trashed. A closer inspection identifed water has indeed made it into the heater. A disaster waiting to happen.

Might work great in a tank containing small fish (like guppies and tetras) but this heater cannot be recommended in anything containing fish of anything approaching substantial size. The heater certainly should not be considered for an Oscar Tank (or any large cichlid). You'll also need to apply caution when performing maintenance or cleaning. A decent accidental bump of the heater against the glass may cause breakage.


Pros:

  • Steady Temperature: While it lasted, it maintained a very steady temp.
  • Appearance: Disregarding the marketing hype, the heater is a sleek looking heater and the blue light (means on) indicator is cool (in the true sense of the word).
  • Easy to Adjust: The temperature knob is very easy to move in small increments, which allows for smooth adjustments of the temperature.

Cons:

  • The darn thing has cracks in it after 3 months of use, from nothing more than a Pleco.
