Don’t settle for an atypical gravel. Natural dramatic colors and textures combined with pH make stronger characterize our coralline and seafloor products. These are coarser materials suitable for most under gravel filtration and fish systems or as an accent for finer sands anywhere where elevated pH values are desirable. Imagine the coralline products in brackish or cichlid aquariums (Central American or African). seafloor Puka shell substrates are great additions to fine sands in reef tanks where animals make their homes by burrowing in the substrate. Jaw fish, blennies and burrowing crustaceans will especially appreciate the extra “construction material.” our substrates are purposely engineered and freed from impurities such as ash, metals, pesticides, and silica; which lets you create a secure and beautiful environment for your fish and invertebrates. Precision grading makes system design a breeze! it doesn’t matter what type of system you are putting in, we have the substrate that’s perfect for the filtration method and habitat you are creating.
