Aqua Base Sky Black Aquarium Gravel, adds interest to your aquarium. The bright colours in your aquarium will stand out against the dark substrate. Gravel provides a pleasant environment for your fish, and it helps to reduce stress. Fish like to dig around in the gravel for food.
Gravel also acts as an anchor for flora.
Over time the gravel becomes dirty, as uneaten food and fish waste can build up, and must be cleaned. Use a gravel cleaner to hoover up the debris from the gravel (without removing the gravel from the tank) see our selection of gravel cleaners
