Review on 🐢 Mylivell Submersible Auto Thermostat Heater for Small Fish Tanks & Turtle Tanks - 5-10 Gallon, 50W by Julie Burton

I used this in my 7.5 gallon shrimp tank and this is my second tank with the same issue. After a few weeks, he began buzzing, making very audible noises, and then died altogether. I managed to capture this video just as my second one was beginning to die. I hooked it up to an Inkbird controller so it couldn't do any harm, but I wouldn't trust it without it and there are very serious concerns about its longevity.
