Prodibio Alka Reef+ Water Conditioner for Aquariums supplies carbonate ions to maintain optimal levels of alkalinity in reef aquariums. It has numerous advantages, including helping to reduce unwanted pH variations and containing carbonate ions to keep your aquarium at its optimal alkalinity level. It works with Calci Reef+, a calcium hydrogel that slowly releases hydrogen carbonate ions into the water, and Alka Reef+, which is gluconate-free. The calcification reaction consumes calcium as well as carbonate ions (with Calci Reef +).
