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, but it can also 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.
Also available in bags of 10kg and 20kg
