Hi Ace,

the FaunaMarin Ultralith-System is a ultra low nutrients zeolith system. It is similar to the zeovit-System of Korallenzucht by Thomas Pohl. I tried both systems but I really prefer the ultralith system as it is - in my opinion- much easier and cheaper than the Zeovit-System with excellent results.

If you have further questions I would recommend to use the link above to the FaunaMarin board at reefcentral, I am sure Claude (the owner of FaunaMarin) will answer all your questions.
