The JBL PROTEMP Cooler x300 is an essential technical device designed to prevent dangerous temperature spikes in freshwater and marine aquariums during warm summer months or in heavily heated rooms. Utilizing an efficient cross-flow fan system, it generates a wide stream of air across the water surface, safely lowering the aquarium temperature by 2 to 4°C through natural evaporation.
Note for Beginner Aquarists: High water temperatures (above 30°C) drastically reduce oxygen levels and can put immense stress on fish and live plants. This whisper-quiet, low-voltage cooling fan provides an easy, reliable safeguard to keep your aquarium's ecosystem stable and comfortable without requiring complex refrigeration chillers.
Short Description & Highlights
The JBL PROTEMP Cooler x300 features a sleek, 360° rotatable housing with an adjustable airflow direction to suit diverse tank setups. Engineered for easy rim mounting, it secures effortlessly onto aquarium glass panes up to 2.4 cm thick. Operating on a safe 12V extra-low voltage and equipped with a protective cover grid, it is an ideal plug-and-play cooling solution for beginners managing medium-sized aquariums.

Detailed Beginner Guide & Operation
1. Simple Installation & Placement
Mounting the cooler requires no tools. Simply place the bracket onto the outer edge of your aquarium rim (up to 2.4 cm thick) and tighten the secure clamp screws. The 360-degree rotating housing lets you angle the airflow precisely across the water surface for maximum evaporation efficiency.
2. Safety & Automation
Operating on a secure 12V low-voltage current via an included universal power supply, the unit ensures maximum safety around water. It also features an integrated safety protective grid. For ultimate convenience, beginners can easily pair this cooler with an optional external temperature controller (such as the JBL CoolControl) to automate operation based on target temperature thresholds.
3. Maintenance Tips
Due to the evaporative process, your aquarium will experience regular water loss. Beginners should monitor water levels weekly and top off evaporated water exclusively with fresh, dechlorinated RO or distilled water (not salt water, to prevent salinity spikes in marine setups) to maintain stable water parameters.
