Reef Casa Frag Rack — Magnetic Coral Anchor System Karbon 7 or 11 Frags - Reef Casa

The Reef Casa Frag Racks are coral frag holders featuring Reef Casa's exclusive Karbon anchoring system. This innovative system grips frag plugs and holds them in place, preventing corals from being knocked over by fish, invertebrates, or strong water currents. The open-branch design ensures optimal water circulation through the frags, reducing stress and promoting growth. Designed and manufactured in Canada with interchangeable neodymium magnets.

Available in 4 variants to suit all aquariums:

Installation and Use

Place the external magnet on your aquarium wall at the desired location. Align the rack inside — the magnets will attach through the glass. Insert your frag plugs (max diameter 28.6 mm) into the slots — the Karbon anchoring system automatically grips them. Position the rack in a moderate light area for new frags during acclimatization. Move to a more intense light area once corals have adapted.

Frequently Asked Questions

How to choose between Goby, Hammerhead, Barracuda, and Great White?

The choice depends on two factors: the desired number of frags (7 or 11) and the thickness of your aquarium glass. Reef Casa aquariums have 5-6 mm glass — the Goby (7 frags) and Barracuda (11 frags) versions are sufficient. For other brand aquariums with thicker glass (8-12 mm), choose Hammerhead (7 frags) or Great White (11 frags) for a stronger magnet.

Is the Karbon anchoring system compatible with Reef Casa Frag Plugs?

Yes. Reef Casa Frag Plugs (25 mm head) are perfectly compatible with the Karbon anchoring system, which accepts plugs up to 28.6 mm in diameter. The Karbon system grips the plug and prevents it from falling even in strong currents.

Can I change the magnet of my Frag Rack later?

Yes. The interchangeable design allows you to replace the magnet with a stronger or weaker model depending on your needs. If you change aquariums, you don't need to buy a new rack — just change the magnet.
