Phosfiltrum experiences and tips?

[Ikikimo]

Hello,

I just purchased some phosfiltrum from an LFS. I was unable to find much of anything on it. Does anyone have any experience with this product?

TIA

It is a brand of GFO. Peoples experiences with most any brand should be relevant. It is a fine way to reduce phosphate, as long as you are careful to not drive it too low.
