Review on 🐠 VIVOSUN Aquarium Heater: Submersible Titanium Fish Tank Heaters with Intelligent LED Display and External Controller by Greg Festa

This is an excellent warm-up. I bought this for my South American cichlid tank and have since purchased a $50 Petco heater. The day before I moved my fish to a new, larger tank, I installed both heaters to bring the water up to temperature quickly. Well the next day came and I removed the VivoSun heater and my temperature dropped faster than Hillary was deleting emails. Pulled out an expensive heater and heard it broke. Put that cute, ceramic-coated, remote-controlled heater back in place and temperatures will start to rise, just like the Trump economy. I will order two more of these as a backup as the heaters often go out but this thing has got my new cichlid tank looking great again. The update just got my third heater. Gradually I transfer all my aquariums to it. My 12 inch Oscar didn't even break the one in the tank and it's the clumsiest fish I have.
