Magnetic Coral Frag Rack Medium MAX - Strongest N52 Magnets

In this review we look at the Magnetic Coral Frag Rack Medium MAX from Reefing Art, a purpose-built frag rack designed to add display and grow-out space on the aquarium wall. The single biggest reason to consider this rack is its magnet system: two pairs of waterproof N52Max neodymium magnets that are triple sealed to provide exceptional holding power on typical aquarium walls. For reef hobbyists who need a stable, clear display solution that fits 5/8' thick glass or acrylic, this rack delivers reliable performance and clean aesthetics.

Key Features

• Size and fit: The Medium MAX 8' x 4' footprint provides a compact but useful planting area that fits most standard aquariums and sump walls.
• Magnet system: Two pairs of waterproof N52Max neodymium magnets are triple protected to keep the rack firmly attached and resist corrosion in the aquarium environment.
• Frag capacity: The rack accepts up to 27 small 1in frags or 13 larger 1.5in frags, giving a clear plan for how many corals can be displayed or grown at once.
• Material clarity: Made from high quality crystal clear cast acrylic to minimize visual distraction and let coral color and growth take center stage.
• Hole compatibility: The 1/2in frag holes are sized to fit most common frag plugs for easy mounting and repositioning of specimens.
• Construction: Designed and manufactured by Reefing Art using top grade materials to provide one of the strongest frag racks on the market.

Who It's For

The Magnetic Coral Frag Rack Medium MAX is aimed at hobbyists who want a neat, secure, and professional-looking way to display or grow multiple coral frags on the aquarium wall. It is especially well suited for reef keepers using 5/8' thick glass or acrylic walls who value magnet strength and a low-profile appearance.

It is less appropriate for those with much thicker walls than 5/8' or for hobbyists who need extremely large planting areas; larger racks or integrated frag systems would be better for heavy propagation operations. Also, if every frag plug you use is significantly larger than 1/2' hole compatibility, check plug dimensions before purchase.

Pros & Cons

Pros

• Excellent magnet strength from N52Max magnets keeps the rack steady even when loaded.
• Crystal clear cast acrylic construction looks tidy and puts focus on corals.
• Good frag capacity for its size, allowing 27 small or 13 larger frags.

Cons

• Some users note the round holes can be slightly smaller than expected for certain plugs, so compatibility should be confirmed.
