Just to give a up date I removed the filter sock and what do I find to my supprise pods. I dumped the sock fast and replaced it with a mesh bag. I am happy with the results. the water passes throught them faster.
I've been using filter socks for years..they just keep my water clearer then mesh bags etc..people think I run ozone. It just more time consuming to clean every 3-4 days and trying to save as may pods/critters as possible...
