Over Heat Protection

The aquarium heater will automatically shut off once the water temp is over 97°F, which effectively protects your fish from “cooking” in high temperature. In addition, it intelligently maintain the tank water at the constant temperature you set. It stops heating when water temperature reaches to the set temperature, and restarts heating when the water temperature is 1°F to 2°F lower than the set value.

This aquarium heater tube is made with heat-resistant quartz glass which is excellent in explosion-proof, and can be used in fresh water and salt water aquariums. The heat-conducting media white alundum sand makes a longer service life (3 years or more).

For Small and Medium Size Fish Tanks

This is a small and compact heater that is suitable for small and medium size fish tanks, such as betta tank, shrimp tank, and snails tank. The 50 W heater is suggested to be used for 5-15 gallons tanks. And the 100 W heater is suggested to be used for 10-30 gallons tanks. However, if the room temperature is lower than 50°F, you may need to buy a larger wattage heater for the same tank.

Answer:  Hi, wich kind of filter you want to put the heater in? Is there are enough of water in the filter to keep the heater never out of water? Please note the 50W heater is about 5inch long.

Answer:  I don’t think so. Just adjust you temperature to 70’s. Or in the green area of an aquarium Temp gauge. Most likely if too hot you can hurt your fish and others in tank. This heater has a temperature gauge and is very accurate . Keep an eye on temp and you should be ok.

Answer:  Hi, as for the suction cup issue, please contact the seller to ask for help.

Answer:  50w shouldn't be too strong. Even when I crank it up to the full 82 degrees on my five gallon (which hold 3 gallons of water) it only gets to 72 or 75 degrees max.
