Filter sock... Yes or no?

[Reef Pilot]

If you are going to use a filter sock, I would recommend going with the 7" size vs 4" to last longer before changes. I use a 7" 200 micron felt sock with my 130 g, and it lasts about a week before it needs to be changed.

If you do a search there have been a few threads on filter socks recently, and how to clean them, etc.

I only started using filters socks recently. My sump is definitely cleaner, and my skimmer neck doesn't accumulate gunk on it as quickly, so it requires less cleaning, too. And for sure my water in the display tank is clearer, with less fine particulate noticeable in the flow stream.
