Review on 🐠 Hygger Titanium Tube Submersible Saltwater Tank Aquarium Heater with Digital Thermostat, IC Temp Controller - 50 to 200 Watt by Gary Davis

Great little heater, I will definitely be buying these for my larger aquariums too! It is visually very appealing in the pool and the controls are easy to use. When I installed this heater on a new tank, I intentionally added water that was about 4° lower than when I installed the heater. A few hours later I came back and checked, the temperature was exactly 76 degrees, right where I set it. The temperature is stable, without jumps, falls and rises.
