Aquarium External Filter Diversa CLARO 1000

Diversa CLARO 1000 is an external aquarium filter designed for mechanical and biological filtration. It delivers continuous water circulation and filtration outside the aquarium, supporting clear water and stable conditions for freshwater and planted tanks. The unit connects to the aquarium with standard hoses and accommodates filter media for removing particulate waste and promoting beneficial bacterial colonization.

Advantages

The external layout reduces in-tank equipment clutter and simplifies maintenance. Its design separates mechanical and biological stages to improve water clarity and nitrification. The filter supports flexible media arrangement, allowing customization for specific aquarium needs. Quiet operation and steady flow contribute to a stable environment for fish and aquatic plants.

Suitable for

• Home freshwater aquariums and planted tanks
• Systems requiring mechanical removal of debris and biological nitrification
• Aquariums where external placement is preferred to maximize internal space

Key specifications

• Type: external canister filter for aquarium use
• Filtration stages: mechanical and biological filtration capability
• Installation: outside the aquarium with hose connections
• Flow control: adjustable flow setup via manufacturer-recommended settings
• Media compatibility: supports standard filter media for mechanical and biological filtration

How to use

Install the Diversa CLARO 1000 outside the tank on a stable surface close to the aquarium. Connect the intake and return hoses securely to the appropriate fittings and prime the unit if required by the manufacturer. Arrange mechanical media (sponges or floss) in the first chamber to capture debris and place biological media (ceramic rings, bio-balls, or porous blocks) in subsequent chambers to promote beneficial bacteria. Adjust flow according to aquarium size and livestock needs, following manufacturer instructions for initial setup and priming.

Usage recommendations

Perform regular maintenance by rinsing mechanical media in aquarium water during water changes and replacing or cleaning media as needed to maintain optimal flow and biological performance. Verify hose connections and seals periodically to prevent leaks, and set flow to provide adequate circulation without stressing fish or plants.
