I am wondering what all of the NON Filter Sock Users do for running drain lines into the skimmer section and prevent massive bubbles and salt spray. I currently just run the braided vinyl drain lines into the sump and I am thinking of changing it up. I have seen the reverse durso but am seriously considering just cutting a piece of Styrofoam to fit nicely on the water surface and possibly notch out holes for my drain lines to go through...Is that OK to do?
