Tunze 9012 Internal Skimmer for Larger Marine Tanks The Comline Skimmer 9012 is designed for aquariums that need stronger skimming than compact nano units can provide, while still keeping the skimmer inside the aquarium or filtration compartment. Its internal Comline design helps reduce plumbing complexity and leak risk while providing consistent organic removal for fish and reef aquariums. Comline 9012 Skimmer Performance Features Large internal skimmer: Recommended for marine aquariums from 300 to 1000 L depending on organic load. Surface suction: Helps remove surface film and organic-rich water from the aquarium surface. Strong air intake: Approximate 400 L/h air capacity supports effective foam production. Large collection cup: 0.7 L cup provides practical capacity for larger systems. Anti-Overfoaming design: Helps stabilize skimming behaviour and reduce excessive overflow risk when conditions change. Quiet internal format: Designed for low-noise operation with Silence Magnet Holder support. Simple maintenance: Cup and foam reactor are designed for convenient cleaning.

Bioload adjustment: Use lower aquarium-size expectations for SPS systems, heavy fish loads, or very low-nutrient reef targets. Surface intake clearance: Leave the intake open so the skimmer can remove surface film effectively. Water level stability: Consistent immersion depth supports stable foam height and repeatable performance. Tunze 9012 Setup Directions Install the skimmer inside a seawater aquarium or filtration chamber at the recommended immersion depth. Secure the skimmer with the Magnet Holder on clean glass within the supported thickness range. Keep the surface intake open and avoid blocking the skimmer body with rockwork or equipment. Allow a break-in period before making final performance judgments. Empty and clean the collection cup regularly to maintain stable skimming. Disconnect power before cleaning, servicing, or repositioning the skimmer. What's Included Tunze Comline Skimmer - 9012 body with foamer Magnet Holder Collection cup Silencer and accessories
