Aquarium Sys Visi-Therm Submersible Heater 300W Review

Average Reviews:

(More customer reviews)I bought this because the heater I had on my 55 gallon tank wasn't doing a good job of keeping it between 75 and 80 degrees. I set this one between 75 and 80 and my tank stays a constant 78/79 degrees.

The Aquarium Systems Visi-Therm Submersible Heater is completely waterproof and submersible, and the best mix of accuracy and price on the market. It features a visually adjustable temperature regulator and an easy to adjust dial for maximum control and ease of use. An extended-life power lamp indicates on and off cycles of the heater, so you can tell at a glance if the heater is working. The non-ceramic element supports make this heater unusually light which prevents suction cups from pulling loose. Designed for use in both freshwater and saltwater aquariums. Extremely accurate magnetic switch for precise temperature control. Mounting brackets and 2 suction cups included. Size: 14"long, 300 Watts (For aquariums between 55 - 100 gallons)
