Review on MUCH 500W Auto Thermostat Submersible Titanium Aquarium Heater with Intelligent LED Temperature Display and External Controller for 70-80 Gallon Saltwater or Freshwater Fish Tanks by Anna Dominguez

BUYER ATTENTION! It failed after 8 days of use costing me dead coral from parasitic stress. I went for a few days and came back to some dead coral and the rest was on the verge of dying. The top of the heater opened up revealing the electronics. I was very shocked when I put both hands in the aquarium to pull out the coral. I had to spend money on a high quality branded product. It's garbage.
