Brightwell Aquatics Liquid Reef – Complete Calcium, Carbonate & Mineral Supplement for Corals & Reef Aquariums – Supports Growth & Alkalinity – No Phosphates, 2L

Brightwell Aquatics Liquid Reef is a highly concentrated calcium and carbonate supplement designed to support the skeletal development of corals, clams, and reef-building invertebrates. It contains 140,000 ppm of calcium, along with strontium, magnesium, and potassium in balanced aragonite ratios. This ensures optimal conditions for coral growth, improved alkalinity, and enhanced reef stability. Unlike traditional calcium supplements, Liquid Reef has twice the calcium relative to carbonates compared to natural aragonite, making it a powerful solution for maintaining reef chemistry. It also stabilizes pH, promoting healthy coral polyp extension and skeletal formation. The silicate- and phosphate-free formula prevents unwanted buildup, ensuring clear water and a balanced marine environment. Perfect for SPS and LPS corals, clams, and other reef organisms, Liquid Reef is an efficient alternative to complex calcium reactor systems. For best results, dose according to calcium consumption and use alongside Brightwell’s reef chemistry products to maintain a healthy marine ecosystem.
