JBL ProTemp S aquarium heaters use modern technology for both freshwater and marine tanks. A protective plastic guard prevents fish burns and protects the quartz glass. It has a safety shut-off if overheating occurs (e.g. when left out of water). The heater is fully submersible, compact, and easy to install vertically. Temperature is adjustable from 20–34°C via a clear dial, with an indicator light showing operation. Using a thermometer is still recommended for accuracy.
