[Skimmer Juice]

where is the best place to get aquarium plumbing parts ?
I have already been to concepts got most of what I need byt still looking for some other parts . Have also been to rona . Is there such thing as a hose barb (plastic) to 1inch slip?

I have a 1 inch bulkhead on my return the bulkhead is thread/thread and the guy I bought the tank from had silicone the bulkhead so I dont want to change it . I'm trying to add a ball valve to the pump so I can shut it to feed . Right now it has a check valve that never works . So as it sits it has soft hose with hose clamps then a hose barb to a reducer to fit the mag 18 pump .

Tried to use a threaded to slip fitting but it leaked at the bulkhead , could not get it to stop , this piece



if /i could find this part to fit 1inch pipe it would be nice , or if anybody has any better recommendation
