Maybe i'm not very observant but ive never seen this for sale before. I've just got some from derek for my L180 juwel tank. It lasts for a year(probably a lot longer) and is fairly cheap. Its nice to have some bio media in the filter rather than all sponges.

Anyone else use it in their juwel tanks?
