Fish Guards Submersible Aquarium Heater 50W with Heater Guard Bundle CUSTOM HEATER GUARD FOR A BURN + SHATTER PROOF HEATER! - Aquarium Heater injuries for your fish can be deadly! Your Submersible Aquarium Heater comes with a Guard acting as a buffer between your fish and the hot heater with fitted dual suction cups so fish/turtles/plants can't get burnt. Plus your special Bonus "5 Things You Absolutely Must Know Before Getting Your Next Fish!" 1-Page Cheat Sheet in your email right away to be armed with little known knowledge when choosing your next fish! AUTOMATIC HEAT SENSING CYCLE TECHNOLOGY WITH INDICATOR THAT STOPS HEATING WHEN TEMPERATURE IS REACHED! - Our Fish Tank Aquarium Heater has two pieces of different metals bolted together to form a bimetallic strip! Once hot enough, the metal expands more than the other so the whole strip bends. Once it bends so much it breaks open the circuit. When the "bridge is up" the electricity instantly switches off and the heating cuts out, giving your aquarium consistent heating and ideal warmth. PREMIUM QUALITY BUILD & ECO-FRIENDLY! - The Best Aquarium Heater for Value! Premium build made using material designed to give you the most consistent and safe aquarium heating backed up with our custom attached heater guard. It's simple to use with an easy to control thermostat, and is suitable for all sorts of fish & aquatic pets. Will look good with your pump, filter, arline tubing and other aquarium accessories! SIMPLE BUT POWERFUL DESIGN! - User friendly and ready out-of-the box design that strikes a balance between function, form and safety! Slide on the heater guard and attach to your aquarium using the Dual Suction Cups! Your heater will automatically turn off as the temperature rises above the internal setting you choose, and turns back on like clockwork once it sufficiently cools down! Customers even use our heater for 10 gallon and 20 gallon tanks!
