Pros & Cons

Update Pros and Cons

The AI used to provide these results are constantly improving. These results might change.

Pros

The only drawback is the size. No complaints other than the slight inaccuracies. Works perfectly with my fluval flex. My goldfish gals are happy as can be.

Cons

Barely budged the temp. I have to hold the heater a certain way to get the dial to move. Not only not accurate to dial, changing the temp with the dial is loose. I am worried about continuing to use this heater if it’s running at the highest setting a... Read More

The m200 is for up to 60 gallons it's not sufficient for my 55 gallon tank. Left it in the aquarium overnight and turned on the next morning.

Kind of disappointing. This heater is junk.

First delivery, no product was delivered only a cardboard insert. The packaging says that there is a 3 year warranty. Amazon has no function that works this way to my knowledge.

Highlights

The AI used to provide these results are constantly improving. These results might change.

Quality

The suction power is amazing and i don’t have to worrry about the heater moving!

The mounting is especially solid and sleek as well.

Finally sprung for an adjustable and using only 1 fixed and thisnow i'm getting 80 day, 79 at night.

Blue light is midway down on the thermometer and is on while heating.

Price

Reasonably priced and fluval quality has never let me down before.

It’s also not very expensive for the sheer quality you will receive.

Great price for a small heater, good product

Packaging/appearance

Packaging is poor however, fell out of the packaging when i was removing it from the amazon box.

But whoever packed this for shipping really needs a class on how to pack a fragile, glass, heater used for someone’s investment.

Competitiveness

This works a lot better than previous ones i've purchased.

But i will say, this heater is a lot nicer to look at than those chunky black ones they sell at petco!

After losing a tank of tropical fish due to a bad heater, i will only ever trust fluvial brand heaters.
