JBL ProFlora m502

Plant fertilizer system with a refillable cylinder and night shut-off key.

Main Features:
• CO2 fertilizer system for better nutrition of fast and slow-growing plants in freshwater aquariums up to 600 liters.
• Assemble the system, fix the air diffuser in the aquarium, and adjust the CO2 supply until the permanent test indicates the optimal value.
• Professional aquatic care with night shut-off: precise dosing thanks to the pressure reducer, even release, effective distribution thanks to the extendable air diffuser, better control thanks to the bubble counter, CO2/pH test, display of remaining pressure on the pressure gauge.
• Refillable cylinder with excess pressure relief, tested by TÜV. The holder ensures the cylinder does not fall. The screw hose connection prevents hose slippage, and the check valve prevents water from entering the cylinder.
