🐢 HITOP Non-Glass Adjustable Aquarium Heater: 50W, 100W, and 300W Options, Ideal for 10-50 Gallon Tanks, Submersible with Thermometer - Perfect for Turtle Tanks and Betta Fish Review

This thing is set at 79 degrees but my fish tank is set at 90 degrees! If I hadn't touched the aquarium glass with my hand I might not have noticed until my RARE puffer was killed. I am very angry. When it comes to heaters, buy a more reputable brand. Lesson learned!

When looking for an aquarium heater, start with a 30 gallon tank. This heater is great for its size. Also, this heater is too hot, so I rate it excellent. You need a good heater, this is your friend. How long does it heat up? Yes, but giving it a few hours works very well. I prefer that to everyone else.

The temperature controller is a joke. The indicator lights up constantly and does not turn off automatically. Also the temperature gets a bit warm but given what I need it for and the price I would have spent more time and energy returning it. Didn't see all the helpful reviews until I got it and realized it doesn't work as advertised. I wouldn't recommend it unless you really need regular ng. It can cook your pets.

I've had this product for a while and it does the job. It keeps the water warm and does not harm the aquarium. 🐟 I don't think it will fit 20 gallons due to its length. 🐠 If you don't clean the top, marks will remain on it after a while. But a simple scrub will get rid of it. 🧼 The suction power is excellent and it has never come loose from the back of the tank since we put it on.

Don't buy what you make. Suddenly killed all my blue angelfish after a year of use. The regulator failed and my fish was cooked. I have a 65 gallon tank and it heated it up to over 100 degrees in a few hours. I left for a few hours when I came back? My fish was cooked. I tested in a 5 gallon bucket and it only took me a minute or two to have 90s. Then I threw it away. This product should not be sold until this defect has been corrected. 😖

This heater stays on all the time when it should turn off when the water reaches the set temperature. I have to constantly monitor the temperature throughout the day and unplug/plug it in when needed. As stated in the description, there is no indicator light to show if it is working or not. If it were, it would always be on! One end has signs of corrosion on the ceramic and appears to be the only part that gets hot. The plastic on the other end where the "temp knob" is has developed slime which

I used to have glass tank heaters and yes, one day I broke down and electrocuted everyone in the tank. I thought of this when I was looking for a heater for my new aquariums. I saw that this one has a coated metal tube so breaking shouldn't be a problem. I bought 2 and both installed, each is capable of heating the tank so if one fails the tank temperature is maintained. They are very easy to use, there is a small dial at the top, just turn it to the desired temperature. I found them correct…
