Review: Reliable and Low-Key (in the Best Way) - This Fluval heater is a solid piece of equipment. I’ve had it running for almost 2 years now and it’s still performing like a champ — keeps the water at just the right temp without any fuss. The borosilicate glass design is a nice touch — it blends into the tank much better than those bulky, obvious heaters. You can still see it, but it’s not screaming for attention. The temperature dial is easy to use and overall it feels well-built and dependable. If you’re looking for a heater that just works and doesn’t make your tank look like a science experiment, this is a great pick. Its a good size, nice and slim and definitely worth every penny.
Review: Great brand great heater - It works great and lasts longer than some other heaters. But like all heaters they do go out after some time. I like how easy it is to set but wish it had a digital display showing the temp instead but that’s a personal preference. The suction cups is amazing and I haven’t had any issues with them coming undone this is a big thing for me. I would recommend this product. Also it holds the temperature at the correct temperature that I set it too so no complaints.

### ⭐⭐⭐⭐⭐ Don't go by dial readings
*by J***F on December 4, 2025*

I have a 100-watt M in a 9-gallon shrimp tank set at 72.5 degrees and it keeps water temp at 76.5 which is needed. My new 150 watt is set at around 80.5 and it keeps water temp at 76.5 and my Angel fish is content with good appetite. I own all three fluval heaters and fluval M has the best (profile) dam best looking heater out there I think, and closest wattage for my 36-gallon tank. Once you tweak settings you can sit back and enjoy.
