breeding rack

[phear]

hi guys im going to set up another breeding rack but this time i am going to plumb the tanks just wondering if u guys have any cheap options for plumbing please reply i am going to have a 3teir stand with 7 tanks into 1 pipe into my uv before it hits the sump so that any disease is killed before it hits the sump and goes back please post some pics of fittings or places to buy cheap but decent fittings.
