Sourcing bits for bubble buckets

Hi everybody!! (Nick Riviera voice)

I'm going to try making bubble buckets for a sort of recirculating DWC. I need to find a supplier/catalog for the fittings that I will install in my buckets and reservoir. i could not find anything at Lowe's that worked ... everything is either threaded or has those Raindrip compression fittings.
Which bits do i need to safely solidly install 1/2" and 3/4" barb fittings in my buckets and reservoir? Who makes full-diameter low-profile ball valves and valve manifolds?
Thanks!
cheers 'neer

search "aquatic eco systems"
free catalog------have everything you need

I bought my bulkhead fittings here http://www.bulkreefsupply.com/store/3-4-uniseal-bulkhead-alternative.html
I too have been looking for an all in one bulkhead fitting with a small ball valve and threaded end that will except a garden hose, like my EZ-Cloner. I haven't found anything like that so far, if you find one post a link i need a few.
