Marine Invertebrates care guide

Water

Stable SG 1.024-1.026 · 24-26°C · low nitrate - stability is everything

Important

Never use copper-based medications - copper is lethal to invertebrates

Acclimation

Slow drip acclimate 45-60 minutes - inverts hate sudden parameter swings

Feeding

Most graze algae and detritus; target-feed larger inverts as needed

Species-specific husbandry lives on each product page. Every fish is quarantined, and every coral dipped and pest-checked, before sale.
