TMC Eco Reef 4kg (coarse)

TMC Eco Reef Sand – Coarse Grade 

TMC Eco Reef Sand (Coarse, 10kg) is a sustainable, natural substrate specifically designed for marine and reef aquariums. Made from 100% British sea shells, this eco-friendly sand provides essential calcium carbonate to help buffer and stabilize pH levels, creating an ideal environment for corals, fish, and invertebrates.

The coarse grade offers excellent water clarity and is less likely to become suspended in high-flow reef setups, making it ideal for tanks with strong circulation or burrowing livestock. Unlike aragonite or mined substrates, Eco Reef Sand is sustainably sourced and has a low carbon footprint—no bleaching, no dyes, and no artificial additives.
