Just built a 40B wet/dry with 2-4x14 300mircon socks. The socks can't handle the flow. Est. of 750gph, ridiculous. Its gotta be a design flaw. I think that it might be b/c they are submerged. I read where some people are mounting them 1/2 to 2/3 out of the water. Is this neccesary to get the flow problem fixed. I submerged them to make it silent. If I have to raise the socks, how do I go about quieting them down. Want to avoid the splash and whitewater torrent b/c its in our livingroom.
