Review on 🐠 InkbirdPlus 300W Submersible Aquarium Heater - Titanium Fish Tank Auto Thermostat with LED Digital Temperature Readout and External Controller - Ideal for Saltwater and Freshwater Aquatic Environments by Katie Johnson

The 300w heater already outperforms the two heaters I have had: the Oase and Fluval M series, both 200w units struggled to fit a 75g tank to hold 80 degrees. It's cold here in the basement. It remains at a constant level of 82. The vise-like heater holder is already outperforming the other two old heaters that were constantly being knocked out by fire eel sprouts. It stayed in place for the last two weeks that I've had it. I am very satisfied with this heater and will buy the next heater from this brand. I love its suction cups, the vise is gripping, the way it's designed, it's amazing.
