The artificial reef system comprises hollow formed shapes (2) constructed from ceramic, plastic or similar mouldable material, textured and shaped to resemble natural rock or coral. The shapes may have apertures 6 and an opening (3) optionally sealed with plug (4) to allow water circulation. The shapes may further be filled with foam 7 or other high surface area material, in a preferred embodiment, this filling is a foam insert. The filling provides a surface for bacteria to colonise thus water passing through the shapes is biologically filtered. The filling may also provide simple mechanical filtering of the water. To provide active filtering of the water the shapes may be connected to a water pump or power filter. |
