Caribbean Crushed Coral (40 lb) 3.0 - 6.0 mm - CaribSea

CORALine - Don't settle for an ordinary gravel. Natural dramatic colors and textures combined with pH support characterize our Coraline and Seaflor products. These are coarser materials suitable for most undergravel filtration and fish systems or as an accent for finer sands anywhere where elevated pH values are desirable.
