Caribsea florida crushed coral - 40lbs

CaribSea Aragonite products set the standard for quality, consistency, and performance, backed by decades of scientific research. Designed for both saltwater and freshwater aquariums (where it will naturally raise pH), these substrates are purposely engineered and rigorously cleaned to be free of ash, metals, pesticides, and silica—helping you build a safe, stable, and visually appealing environment for fish and invertebrates. Available from Reef Supplies Canada for aquarists who don’t want to take chances with lesser substrates.

This is the only crushed coral made with true aragonite, delivering up to 25 times the buffering power of standard crushed coral, dolomite, or oyster shell. It helps eliminate chronic pH issues, provides exceptional surface area for beneficial bacteria, and can support up to a 50% increase in bioload. It never needs replacement and contributes calcium, carbonate buffering, and essential trace elements such as strontium (up to 10,000 ppm).
