Rated 5 out of 5 by from Finally! I bought literally every heater that Petsmart sells trying to find one that would actually keep the temperature. I have a 10 gallon which you wouldnt expect to be hard to heat! This is the one! I have to set it to 75 to get the water to 77 but that's ok. It NEVER goes below 77 and remains steady despite crazy Texas weather. 50's at night...80's during the day and it keeps perfect.

Rated 5 out of 5 by from Excellent heaters! I initially purchased a 200w heater for my 55 gallon tank and because it looks good in the tank and does such a good job heating, I purchased a 100w for my 20 gallon tank. I have been using the heaters for awhile now and I have no complaints. Although there is a min/max line printed on it, I submerged it until just the top temp adjuster is out of the water. The blue light is a lot better looking than most heaters that have a red light. Just remember with heaters, you get what you pay for. This particular heater goes on sale often and for the price, it can't be beat. If anything happened to either one of mine I would purchase another fluval heater. I'm very satisfied.

Rated 5 out of 5 by from No problems. I have both a 50w and a 150w, so far everything has been good. No issues with these heaters plus they aren't to bulky.

Rated 5 out of 5 by from simple, straightforward, effective I've had mine for a few weeks now and I find it's a very reliable product, the water was heated up in around 24 hours, and the temp is steady and constant, the only thing I find is wrong is that the heater slips downwards a little and the heater is more submersed than it's supposed to be, it's only happened twice, and it seems to have stopped, idk why it's doing that, but the water level is just at the limit line, which is fine, but it makes me uncomfortable as I want to conserve the heater and have it not burn out

Rated 1 out of 5 by from Seriously disappointed I had a Fluval heater for a 75-gallon tank I had a few years ago. It was awesome. It kept the tank at the perfect temperature. I recently set up a 35-gallon hex and knew I wanted another Fluval heater. The quality must have gone down since my last purchase because I'm having trouble with this one. It didn't come on until I turned the temperature way up and I only know because the bottom of the tube started getting warm. I don't seem to have the blue light to tell me it's when it's on. I'm seriously considering returning it for a different brand.

How long to wait before I put it in the tank and what temperature to put it on?

Asked by: Anonymous
It says to put it in the tank but let it adjust to the temp of your water for like 30 min before you plug it in. The required temperature depends on your fish, tropical fish in general want around 78 but fish like goldfish and I think plecos prefer a little cooler temp.. tbh just Google your fish

Which size is good for a 5 gallon tank and would it be good for a betta fish?

Asked by: tiffanya601
Go with the 50w but just keep it near your filter so it can disperse the heated water well. It automatically stops heating whenever it reaches the temp you set so it shouldn't overheat your tank.. I don't see how it wouldn't work with a betta unless yours likes to wedge itself behind things ?

How many watts for 150 gallon tank?

Asked by: Jackazee
A 300w but, It really depends on what temperature you want your tank. I'd start with 300w and with the adjustable temperature gauge you should be fine and raise the temp when needed. :)

Is this heater completely submersible? It has a water line on is so I'm afraid to put the whole thing under water.

Asked by: Lstorrie
It is not completely submersible. There are 2 water lines for minimum and maximum levels. I love my heater, but I do constantly check to make sure it hasn't fallen in.
