Rock Media & Sand

Stabilise the PH levels in your reef tank with the help of a high-quality crushed coral sand which also provides a hiding place for many species of fish and critters. In addition to sand we also stock a selection of dry rock, filtration and rock media to help you create a great environment in your aquarium.

From aqua shaping to filtering media we have a range of rock media and sand to choose from for your marine aquariums. Choose from real reef rock, EcoReef rock mix, Hobby snail and crab shell sets and much more. Improve the filtration, PH levels and help to recreate a natural environment for fish and coral in your tanks.

At Kraken Corals we have a fantastic selection of rock media, sand and other filtration media available to purchase online. As well as decorating your tank gravel, rock and sand substrate provides a home for beneficial bacteria and helps to maintain a healthy environment for your fish.

Substrate provides useful hiding places for fish as well as helping to minimise reflections within the tank. We’re always happy to help and provide advice to customers so for any information or help just get in touch with our team today on 01254 235 130.
