The AquaEl 150W Ultra Aquarium Heater is appropriate for aquariums from 24 to 40 gallons. They are the only heaters on the market with solid state thermostats. This means they have no moving parts that can break and cause a calamitous aquarium failure due to the heater not turning off.

The thermostat operates with an exceptional precision (+/- 0.25° C) to maintain a constant temperature in the tank. The other heaters on the market have normal temperature swings of a couple degrees. The constant temperature ensures that even the most sensitive of aquarium animals will stay comfortable at all times.
