Fluval M50 Submersible Glass Aquarium Heater (50 watts)

Love it. Works a great for my 57L fluval flex tank. Looks as if it warms the water without pushing itself to the limit. The control is not very accurate though so watch out for that.

a good product does its job perfectly

Serves its purpose and easy to install

Good little heater, maintains the water temp no problems in my 50l aquarium. Nice and slender also to fit into my filtration compartment. Also have a fluval E advanced which I prefer (in another aquarium), buy it is bulkier and more expensive, however it has a digital readout and advanced features. But the M50 does all it needs to, has an easy to operate temperature knob, and a slender design more suited to a smaller aquarium or a hidden filter compartment.

Best buy for 57 ga;l tank

Great for temperate tanks & fancy goldfish.

I have give this a five star more for the fast delivery and that is came in one piece. I did not use it because it was to big for the tank I wanted to use it for and returned it

Does the job, sadly mine is now stuck and my Betta tank temp has shot up to 84 degrees. Thankfully I have a spare 50w heater.

Excelente artículo, precio inigualable, marca de prestigio con un diseño del equipo elegante que además funciona de manera impecable manteniendo la temperatura del acuario estable.

Formschön und einfach in der Handhabung. Sehr gut.

Très bon chauffage, aucun regret sur son efficacité

Toller Heizstab! Kann ganz unter Wasser gesteckt werden. Schaltet ab und an den Sensor ein, um die Temperatur zu überprüfen. Seit einem Monat im Gebrauch und die Temperatur bleibt konstant. Gut verarbeitet.

Cable is short.
