Hydor Pico Pro Internal Filter – 300 L/h for Small Aquariums up to 45 L

The Hydor Pico Pro Internal Filter is an ultra-compact, 3-stage filtration solution designed specifically for aquariums up to approximately 45 litres. It offers mechanical sponge filtration, biological ceramic rings and a chemical activated carbon cartridge—all in one small unit. 
With a maximum pump flow of 300 L/h, it’s suitable for well-stocked small tanks, shrimp setups or nano displays.
Compact dimensions (6 × 8 × 18 cm) make it unobtrusive inside your tank, and it includes a swivelling outlet nozzle and a venturi kit to increase oxygenation and water circulation. 
Designed safely for shrimp and small fish, the Pico Pro includes a protective grid to prevent accidental suction of tiny animals, and its quiet operation makes it ideal for viewing tanks or low-noise environments.
