Bulkhead question

[Subbedout]

Hi all! I'm very new to saltwater aquariums and just ordered a 66 gallon SCA PNP system (http://www.scaquariums.com/mobile/Product.aspx?id=37540) which is on its way as I write this. I'm plan to hard plumb it and have been researching the best way to do it. I'd like to order colored pvc and get some gate & ball valves as I've seen done in many R2R build threads.

I'm a bit confused about bulkhead sizing. The tank I bought has 3 holes drilled in the overflow box and says it fits 1" schedule 40. Does this mean that I need to order 1" pvc pipe to plumb everything, or does a 1" bulkhead mean that the pipes need to be smaller than 1" (if so, what size)?

Thanks in advance for any help!

If it says it fits 1" sch40 pvc, you'll need 1" sch40 pvc to plumb it.

Thanks! So that means the hole drilled in tank must be larger than 1 inch?

Yes

Yes. A 1" bulkhead requires a 1-3/4" hole.

Don't think already come drilled and with the fittings already?

They come drilled, yes. From what I've read on R2R, many people replace the included plumbing for pvc to hard-plumb everything.
