Fluval P Series Submersible Heater

A slim, factory pre-set heater for nano and betta aquariums, where a full-size adjustable heater simply will not fit.

Key features

• Pre-set at the factory to a tropical community range, so there is no dial to be knocked or misread
• Compact body that disappears into a small tank, fresh or salt water
• Fully submersible, so it can be laid low in the tank where the flow is strongest
• Offered in more than one size — pick the one rated for your tank's volume, or tell us the tank and we will match it

A pre-set heater suits a standard tropical setup. If you need to raise temperature for treatment, or you keep species with unusual requirements, an adjustable heater is the better choice. Mount it near the filter outflow so the thermostat reads real tank temperature, and keep a separate thermometer in the water. More Fluval equipment in Fluval.
