Filter socks

[JPotter]

I have tried filter bags..one hung on each return. In about 2 weks the sock is brown not white and the water flows over the top. There was very little if any detritis but the material just seemed to clog up very quickly. I stopped using them and have seen no difference the rate of visible debris collecting or how clear the water is. I do notice a fine settlement on the bottom of the sump but at the same time as stopping the routine use of the socks I put a black vibration dampening material in the bottom of the sump and a sump light so now anything seems very evident...before it was just too dark to see much.
