Review on 🐠 Quartz Glass Submersible Heaters for CNZ Aquariums by Jessica Romero

Bought to replace another faulty heater; that works great. I've had absolutely no problems with it, I've used it on both 5.5 and 10 gallons with no noise and the light clearly indicates when it's on. Sometimes it warms up by about a degree, but otherwise remains fairly stable. I have recommended it to some of my fishing friends who were looking for a cheaper alternative to the Aqueon Pro.
