How long does it take for your ehfisynth to clog?

I went to back flush my eheim 2215 and fill it up the rest of the way with ehfi substrat pro (they shorted me 3" Well I pulled out my ehfisynth (the fine filter floss) and it looked like a muddy muddy floor matt on a porch. disguisting. It is only about 2 months old. How long do you guys have to replace yours?

It depends on your bioload. I change the white pad in my 2217 every other month. It does look just like a muddy door mat. Everyone's tank will be different.
