Perfect with a little tweak

Perfect heater with a little tweak. I use this one to heat up a 6.5 tank. I'm scared of cooking fish, so a passing reader puts my mind at ease. Previous reviews have reported their betas getting snagged and killed by the heater's suction cup area, so I took one review's advice by wrapping them in loofah webbing. However, I have found that the straps keep a lot of heat in close proximity, so the heater shuts off before the heat has spread to the rest of the tank. My solution was to take the same

  • Cool product

Perfect heater for a small aquarium

I have a 10 gallon aquarium and am struggling to find a 50w heater that fits in the aquarium and is fully submersible. Other heaters I've bought have always been too high and I've had to return them. This heater is ideal for small aquariums. It is compact and fits into any shape, landscape or portrait, aquarium design. This heater was also clearly designed for aquarium enthusiasts, because you can change the temperature without getting your hands wet or removing the heater from the aquarium…

Great way to kill fish in 10 minutes

I'm not the type to write bad product reviews or reviews in general. I have to say this is probably the worst thing I've ever bought. For my daughter's birthday I bought a very nice beta fish which she loved. I thought I would do everything in my power to give the fish a good home to keep them healthy. So this product was one of the first I turned to to keep the tank at a good temperature for this. 10 minutes after she was in the tank, I noticed that the fish was lying upside down on the bottom

Pros
  • Comfortable
Cons
  • Line is shorter than other picks

Tons of questions. in Fish & Aquatic Pets

I can't say enough good things about this heater. However, here is a list of things that definitely need to be fixed -1. Does not maintain a constant temperature. I set it to 24°C and it fluctuates between 23°C and 26°C which is stressful for my fish.2. The cord is not very long, only about 1.20m, luckily my fish tank is so close to the outlet, but I can only use it in this 1 fish tank, otherwise I need an extension cord.3. The red light that shows the temperature setting is very bright. It's…

Pros
  • Great for a small home
Cons
  • Protection

Failed heater for multiple reasons

This heater had been plugged in for less than two weeks when I walked past it this morning and heard howling noises from the room. After pulling some items out of the tank, I found that it was a brand new heater. Please watch the attached video. You will notice that the sounds will start as soon as the heater registers the temperature (stops flashing). I turn it off and on again and the same thing happens. Also, no, my tetras tank is not kept at 79 degrees. The first problem I noticed with the…
