Again today I took apart my filter, very, very carefully inspected each lateral, the standpipe. Everything is in PERFECT condition. The filter for some reason is still letting in a very fine dust. When I vacuum it up I use the scum bags and it resembles pollen it's so fine. I'm hoping that maybe once my media gets dirty it will start to filter out the fine stuff.

My numbers are perfect so I know it's not algae, just took them today:

FC 14
CC 0
CYA 80
ALK 80
PH 7.6

Also when I put a panty hose on the return it catches it all.

I'm just at my wits end.
