Review on 🐠 Aqueon Submersible Aquarium Heater: Optimal Temperature Control for Vibrant Fish Health by Jamie Vanderburg

I bought this because my old river water heater was starting to go haywire. When it arrived I looked at it and when I saw it was intact I removed it. A few months later, when the flux heater finally failed after 10+ years, I pulled this piece of crap out. I put the tank in for 6 hours before plugging it in. He heated the water too much. I set it to the lowest setting of 62 and the water is still around 80 degrees. Back late. Don't buy this. Spend more and get a reliable heater.
