Rock & Sand

Live rock is the most popular hardscape used for natural biological filtration in saltwater aquariums. Aquarium rock is available in two forms—wet or dry.

We stock dry rock as it’s the most eco-friendly option. Our dry rock is either human-made or mined from the ground, meaning that no rock is removed from the ocean. Dry rock has the added advantage of not hosting hitchhiking pests and will not need to be cured like most ocean rock.

Live sand works in a very similar way to live rock, hosting beneficial bacteria in our aquariums. Sand is available live or dry with the live version being packed in water. Several granule sizes are available from sugar-like to coarse crushed coral substrate.
