My old scrubber had 3/4" pvc with screen slot. Sometimes it would clog from the algae or spray anywhere but the screen. On my new build I am using 1" pipe and need 24" of screen slot. The screen's I am using are 12"x18" and I would like to lower them a few inches to prevent algae growing near the slot and have a even flow of water over the screen. I wrapped screen around the PVC and joined a the screen then did a test. The water still does not flow evenly down the screen. I think it's because I used small zip ties.
Suggestions?
