Review on 🐠 AQQA Submersible Aquarium Heater: 100W/200W/300W/500W/800W, External Temperature Controller, LED Temperature Display, Suitable for Marine Saltwater and Freshwater Tanks by David Fields

I bought an 800 watt heater for my 125 chiclid tank, it's been in my basement (basement) for two weeks now and works great. I have almost 200 gallons of water between the tank, first stage bag filter, 50 gallon refugium and wet/dry sump with external pump. It easily maintains a water temperature of 78 degrees Fahrenheit and an air temperature of 64 degrees Fahrenheit. The heating element mounts horizontally in the sump just next to the pump inlet on suction cup mounts at the bottom of the sump. Plug it in, press the + or - button to change the hold temperature, no other controls or programming required. . A good display shows the target and actual temperature as well as heating or idling. I recommend buying this heater. Two 400W VisaTherm heaters cannot match this level of performance.
