Aquaforest AF Pure Food is a 100% natural coral food designed to support healthy growth and calcification in marine aquariums. Its composition, based on calcium carbonate, provides essential micro and macro elements that corals require for robust development. This unique formulation mimics the natural diet of corals, promoting intense growth and vibrant coloration. Additionally, the calcium carbonate base helps maintain stable pH levels in the aquarium, creating an optimal environment for reef inhabitants. For best results, use at least once a week; in mature, well-planted aquariums, daily use is beneficial.
