Zeovit - Enough talk, show some pics

[reef]

Anyhow I'm not exactly sure why we buy the zeolith rock other than a place where bacteria can feed and grow why couldn't they grow on biorings or inside biorock.

You dont need to add the zeolite at all. it is just added to help the cleaning process.
zeovit will work without the zeolite as the bacteria is the partthat breaks down the waste.
