🐠 Energy Efficient Submersible Thermostat + Thermometer Sticker - VIBIRIT Betta Fish Tank Heater 25W, Smart Small Aquarium Heater Review

I bought one of these for a small aquarium that I installed to keep some fish alive after tearing down an old aquarium. The stress of moving was killing the fish so I decided to demolish the small tank after about a week. When I did this I found that the water was quite warm as was the heater. The sides of the heater blistered and melted. still in the water! As you can see from the photo, the heater has melted and discolored. This can happen if you take one of these types of heaters out of the…

Honest; I had no intention of buying this. I tested it in a ceramic bowl before putting it in the aquarium. I wanted to make sure it would work without water getting into the heater and killing my betta instantly! I have a 2 gallon tank. It's PetSmart plastic.

I noticed my beta started losing fins after 4 months. I couldn't understand why. I checked the water for several days to make sure everything was fine. Then one day I put my finger on it and noticed it. I got a slight electric shock. It was the heater after turning off the filter that I had. I took it off and…

I don't usually write reviews but bought this product based on the rave reviews. And let me tell you that I've never been so disappointed. The instructions say it will stop heating at 82. This is WRONG. I felt like checking my temp on my beta and it was at 84.6 and getting STILL hotter. The heater didn't turn off when it was supposed to (the light was still on). I watched it for a while because it kept the right temperature in the morning and didn't get too hot and I thought there must be a…
