Real Reef Base Rock Mix Box : Small - Large

Designed as a sustainable alternative to wild-harvested live rock, this premium rock provides all the benefits of natural reef-building materials without harming ocean habitats.

Made in the U.S.A. using all-natural marine-friendly materials, Real Reef Rock is composed of the same calcium-based building blocks as wild coral skeletons, ensuring a safe and effective environment for reef aquariums.  Contains 2X the available Alk, Calcium Carbonate CaCO3 and more available trace elements than wild live rock.

Each piece is lightweight, porous, and uniquely shaped, maximizing surface area for beneficial bacteria growth. Unlike traditional wild live rock, Real Reef Rock is pre-cured in saltwater and free from nuisance pests, parasites, and unwanted hitchhikers. The rock is pigmented with non-toxic, coralline-inspired colors, ensuring a vibrant, natural appearance that stays rich in purple, pink, and red hues—whether in a reef or fish-only system.

Skip the uncertainty and hassle of curing wild live rock and choose an eco-friendly, bio-active alternative that looks better and performs better—without the environmental impact.
