I like mesh..felt for me is clogged in a day or two and cleaning is painful for felt..and I DO NOT have the permission to wash the socks in our washer
I ran the tank without socks for 1 1/2 year and it clogged my reactors and the sump collected lot of gunk and built up nitrates..wish someone would invent something much easier than socks![]()
"easier" would be an attachement of some sort that made the drain water pass through disposable filter floss.. I've seen some neat DIY's to accomplish this.. no rinsing, just pitch it and replace it..
