Aqua Substrate coarse ‘Coral Sand’ is the perfect Aragonite substrate for all types of marine aquaria and those coldwater & tropical aquariums requiring hard-water conditions (e.g. African cichlids). Not only does it look great as an aquarium substrate, it can be used as a filter media due to the high surface area for biological and mechanical filtration. In either case, it provides a natural media for beneficial bacteria to grow and so help towards keeping your aquarium balanced.
In a marine aquarium Aqua Substrate ‘Coral Sand’ will help to maintain the pH of natural seawater and also provide a source of calcium and other essential trace elements.
All Aqua Substrates have been carefully cleaned beforehand and therefore require the minimum of rinsing before adding to your aquarium.
