Give loose mushroom corals a sheltered place to settle in a reef or frag tank. The PNW Custom Shroom Box mounts magnetically to the aquarium wall and helps keep small pieces from drifting behind the rockwork.

Choose your box size

• Cube — 2″ × 2″ × 2.5″
• Small — 4″ × 3″ × 2.5″
• Low Boy — 6″ × 4″ × 2″
• Large — 6″ × 4″ × 4″

The Cube and Small suit individual pieces or tighter layouts. The Low Boy gives you a wider floor area with a low profile. The Large has the same footprint as the Low Boy with more vertical clearance.

Choose your glass thickness

Measure the aquarium panel where the box will mount. Select the magnet version rated for your glass thickness, ½″ or ¾″. The magnet rating and the box dimensions describe different measurements.

Suggested add-ons

Use appropriately sized reef-safe rubble or frag discs to give loose mushrooms a surface to attach to.
