Effective Marine Aquarium Protein Skimming

The Tunze Comline DOC Skimmer 9001 is designed to help remove dissolved organic compounds from marine aquarium water.

As aquarium water passes through the skimmer, fine air bubbles attract organic substances, carrying them upwards into the collection cup.

This process, known as foam fractionation, helps remove organic waste before it breaks down further within the aquarium.

Regular protein skimming can help support stable water conditions and complement the aquarium's existing filtration system.

Compact Design for Marine Aquariums

The Tunze 9001 features a compact construction designed for internal installation within suitable marine aquarium setups.

Its space-saving design makes it particularly useful where a larger external protein skimmer would be impractical.

The unit can be incorporated into compatible aquarium filtration arrangements while keeping equipment intrusion to a minimum.

Supports Cleaner Reef Aquarium Water

Organic waste can accumulate within marine aquariums from uneaten food, fish waste and other biological processes.

The Tunze Comline DOC Skimmer 9001 helps remove dissolved organic material, supporting improved water quality and reducing the organic load within the aquarium.

This makes it a useful addition to suitable marine fish and coral reef aquarium filtration systems.

Convenient Maintenance

The skimmer features a removable collection cup designed to collect the concentrated organic waste removed from aquarium water.

Regular emptying and cleaning of the collection cup helps maintain effective skimming performance.

The skimmer body, air intake and pump components should also be inspected and cleaned according to the manufacturer's maintenance recommendations.
