GAC question

[Spotted]

Is there such a thing as too much GAC? I have a 120 and I use a reactor with a lot of GAC. I'm not seeing clearer water. I have a lot of particulate floating around and it's driving me nuts!! I was thinking of replacing my sand with a coarser type of sand in hopes that it would cut down some of that floating stuff..
Any thoughts?

Gac won't get rid of floating particulate matter. You need a polishing filter pad. Do you have a sump with filter socks?

Yes I do..

Try smaller micron socks.
