Aquarium Gravel and substrate is just one of the many ways to deorate your fish tank or create your perfect Aquascape.  Coming in a variety of colours and size from tiny pebbles or sand to large calcium carbonate rocks. Gravel or substrate isn't only just for looks! Many gravels and substrates can be used as buffers to stabilise pH or as a suitable soil to keep aquatic plants healthy and vibrant. Gravel can provide a home for beneficial bacteria to grow and flourish as well as reduce the need for water changes. Here at Aquaholics we know the importance of gravel and substrate which is why we stock the best quality Australian gravel available.
