Buying Guide

Match decor to tank type

Choose pieces rated for saltwater or freshwater use and that won’t leach chemicals into reef systems; magnetic attachments and acrylic materials are common for reef-safe decor

Consider mounting and placement

Magnetic frag racks and display pieces with strong N52 magnets or secure attachment points let you position corals without drilling or adhesives, improving access and water flow

Evaluate frag capacity and scale

If you plan to frag or display multiple corals, pick racks sized for the number of plugs you’ll use (for example, large multi-plug racks suit active fragging and propagation)

Prioritize practical reef tools

Long-reach grabbers, feeders, and magnifying viewers help with coral placement, target feeding, and inspection without disturbing the tank environment

Factor in supplemental needs

Coral nutrition products and reef supplements can support growth; choose scientifically formulated feeds sized for your maintenance schedule and tank bioload
