Penn Plax CH16500 Aquarium Heater Review

FULLY SUBMERSIBLE AQUARIUM HEATER: The 500W Warm Tone LED Aquarium Heater easily maintains healthy water temperature, and can be set anywhere between 61 °F and 90 °F, by using the precise adjustment dial. The 500W model works great for 80 – 200 gallon fish tanks. LED DISPLAY: With an easy to read LED display, our Warm Tone Aquarium Heaters accurately show the water temperature, allowing you to monitor and adjust it as needed. ADDITIONAL FEATURES: In addition to being composed of high quality quartz tube and electrical components for maximum safety and durability, these fully submersible aquarium heaters can be placed either horizontally or vertically. PLEASE NOTE: Do not operate heater outside of aquarium, and never submerse a hot heater into an aquarium – only submerse a cool heater. After placing the heater into your aquarium, wait 15 minutes before turning on. This allows the thermostat to adjust itself to water temperature.
