What does everyone use for filter floss?

I have been using the Poly Filter from InTank for past year and its great but coming to an end. What does everyone else use, especially the Uk guys.

I get this from my LFS. Great value and lasts for ages.

I have bought the cheap stuff at the LFS in large sheets. I just cut it fit. It's basically a generic product and is very inexpensive.

I have seen Poly Filter's advertisements. They claim the filter material lowers nitrates and phosphate levels. Did you find that to be true?
