The PVC grid for aeration is 1/2"CPVC pushed together, not glued, so it can be adjusted or modified. There are plugs of polyurethane hot glue in the short pieces that connect the T's together so that each runner is fed individually. It gives a more uniform flow. I wrapped a two inch wide strip of sheet lead on each end to keep the setup on the bottom and in place. I drilled 1/8"holes every 2". Best thing to do when you get you sink is fill half way with water and setup your grid and get it adjusted out before filling with electrolyte.
