Marine Pure Block

Marine Pure is a porous ceramic block that houses nitrifying bacteria on its outer surface and low-oxygen zones deep inside, so it handles ammonia and nitrite and helps bring nitrate down too. It's made for passive or low-flow spots in a sump and works as a live rock substitute. Rinse it before use, and if you need to, you can cut it to fit with a hand saw.
