FEDOUR Submersible Aquarium Heater with Protective Cover, Adjustable Thermostat for 5-40 Gallon Fish and Turtle Tanks - Available in 30W, 50W, 60W, and 120W Options Review

THIS IS DANGEROUS FOR YOUR FISH. The design of the heater is such that it allowed our betta to swim in the thermometer and get stuck in the case, clinging to the heating element. The device has been placed in a horizontal position as described and as indicated in the instructions. DO NOT BUY THIS DANGEROUS ARTICLE FOR YOUR BETA. Luckily I was able to retrieve the fish, but it's not yet clear how much physical and emotional damage will be done. on an animal.

Have been using this heater for about 2 weeks. Looks nice and very big. When I ordered it said I was getting a 50w heater but it is actually 60w. But it works great for my 15 gallon tank. That's too much for anything under 10 gallons. It has a lot of holes and grooves in the tread so I had some issues with my Endlers trying to squeeze it in and test it (they fit). I've read reviews about temperature swings so I set mine a little lower than needed, which I didn't have to do because it was pretty

Okay, this heater is a pain to suck on. Keep in mind that suction power may be better if you install it during initial aquarium setup before adding water. Vacuuming when everything is in place will give you a headache. The description says it's 5-10 gallons, I have a 5 gallon tank and it doesn't fit vertically. It says the whole uuit needs to be submerged in water, you can't do that in a 5 gallon tank so I had to put it on the floor. It's one of the ways he says you can mount it, but it becomes

After spending about 3 hours searching the internet for a good heater, I finally decided this heater would match my in-line filter for my 8 gallon tank. Appearance: beautiful design. , very attractive so not an eyesore if it was visible in the tank.

Accuracy: To be honest it's not very accurate in setting, it's about 6 degrees above normal, I set it to…

I've looked at SO many different heaters here on Revain and read as many reviews as possible to try to find the best one for me (looking for a new heater for my 10 gallon Betta as the old one stopped working after a few months old was also very inconsistent and cheap even before it broke). Is it just me, or presumably every heater ever made has utterly mixed reviews and an alarming amount of 1 star reviews saying "this killed my fish, worst product ever" etc. mixed with a lot of good reviews…

Rating: Great filter, I have (I think) a 20 gallon tank. not completely filled, but until full this heater keeps a good temperature. I have the air conditioning on and the fan running and it can get very cold in my room. Don't worry about my turtles. I've touched the water with my hand it's definitely not cold, just about the temp I set it to (warm), I don't have a thermometer or an accurate form of temperature measurement to see if it's the EXACT temp set, which I put on the filter, but keeps…
