Haha thanks guys. I'll check those out if I need to remake the spray bar if it chips.
By the way, what size tube/hose do you recommend using for a 3/4 PVC pipe? I don't know if I can re-use the hose from my Aquatop canisters. They're 5/8 size. If I can't I was thinking of buying black vinyl hose from Dr. Foster's.
