🐠 Cobalt Aquatics Neo-Therm Pro Aquarium Heaters (Available in Multiple Sizes) - Advanced Dual Display, Fully-Submersible, Shatterproof Design, Precise Thermostat Review

The first 50w unit worked fine for about 2 weeks then I noticed the temperature in the tank dropped to about 76 while the heater was set to 78.

After about a year and a half of perfect heating, my 100 watt Neo-Therm started changing temperature settings on its own, and after a few days it was up to 86 degrees (I noticed the problem and fixed it, later stopping it at 96). degrees in the test tank where I tried to reset it).
