Anyone that runs a ZeoVit system, or has in the past, this is for you. I understand that to make this system work, you must have a ULNS. I have seen some online that are absolutely beautiful. I am currently running an ULNS using EcoBak and GFO, and wanted to know if using the ZeoVit supplements (ZeoFood, ZeoBak, Amino Acids, etc.) would work without using the Zeolith media. Any and all help would be appreciated.
