## Long description

Diversa CLARO 300 is an external canister filter designed for freshwater aquariums. The unit delivers mechanical and biological filtration in a compact canister housing, supporting continuous water circulation and effective removal of debris and suspended particles. Built for small to medium tanks, this external filter integrates layered filter media to maintain stable water quality while enabling straightforward access for routine cleaning and media replacement.
Advantages
The external canister configuration separates filtration components from the aquarium, reducing clutter and noise inside the tank. Layered media support both mechanical trapping of particulates and biological colonization for nitrification. The product is sized for easy installation and service, with connections and valves that simplify flow control and priming. Designed for freshwater use, the filter aims to sustain clear water and healthier conditions for fish and plants without requiring frequent full-water changes.
Suitable for
 Small to medium freshwater aquariums
 Community fish tanks and planted aquaria
 Hobbyists needing reliable external filtration with simple maintenance
 Continuous water circulation and debris removal
Key specifications
 External canister design for out-of-tank installation
 Combined mechanical and biological filtration using layered media
 Compact housing suitable for limited cabinet or stand space
 Inlet and outlet plumbing with integrated valves for flow control and priming
 Designed specifically for freshwater aquarium applications
How to use
Install the canister in a dry, accessible location below the aquarium, connect the inlet and outlet hoses following the supplied orientation, and secure all fittings. Prime the unit as instructed in the user guide to start water circulation. Arrange filter media in the recommended order to ensure mechanical filtration upstream and biological media downstream. Monitor flow and water clarity during the initial hours of operation and check for leaks at connections. Periodically rinse mechanical media and replace or refresh media as required to maintain filtration efficiency.
Usage recommendations
Regular maintenance ensures optimal performance: inspect hoses and seals monthly, clean mechanical media when flow decreases or visible debris accumulates, and avoid replacing all biological media at once to preserve beneficial bacteria. Choose media combinations suited to your aquarium stocking and plants to balance mechanical filtration and biological stability.
