Hi,
The purpose of Foz Down was to reduce the cost and work associated with removing Phosphates.

Seems like more work than GFO.

The reason people want to use filter socks with the Foz Down is the fear that the bound phosphate will be released back into the system. I have never heard of this happening nor have I heard of an experiment to test the theory.
If you would rather not use filter socks then that is your decision. It won't effect your system in a negative way if you don't. I have used Foz Down with out filter socks for several years with no ill effects.
Cheers,
