Proper Bulkhead size??

You may be out of luck going to schedule 80 if your bulkhead holes are glass and pre-drilled. Like coop said the required holes are larger for sch 80 in the same size. You shouldn't need sch 80 for a normal application, and the 1" drain and 3/4" return size is normal.
If your holes are acrylic or another plastic, you can enlarge them with a Dremel with a sanding wheel.

it is an acrylic frag tank but I dont feel comfortable with enlarging the holes myself... I guess I will just stay with the original bulkheads then. I did originally take the bulkheads to Home Depot to find plumbing parts but nothing would properly attach to the male threaded ends. Any ideas of what I am doing wrong?

if I understand you correctly outside threads on the bulkhead are for the lock ring.. you will glue a pipe or a fitting to the inside of the bulkhead

The outer threads of a bulk head are just there for the threaded washer for creating a seal against the glass/acrylic, only the inside of the bulkhead is designed for standard PVC pipe and fittings. You will need male type or just pipe in order to plumb the bulkhead.

Maybe..I just had to add my 2 cents...hehe
Sorry, overlooked it.
All right guys, I must be slow. I went to HD again and none of the fittings in the plumbing section are matching up with these **** bulkheads I have. I want to get this frag tank up and running!!! If there is someone that would be willing to help me out with this tomorrow I'll toss them a couple frags for their time....PM me if youre up for it....
Ditto to what everyone said about sticking with Schedule 40 bulkheads.
If you have slip bulkheads, which is what most people use, you will need a small length of PVC to attach the fittings with. 1" PVC for the drain, 3/4" for the return. Insert the PVC into the bulkhead, and glue with primer and PVC cement, then insert the other end of the PVC into your fitting and prime/glue.
If your bulkhead is threaded (threads on the inside surface) then Teflon tape and a threaded adapter can be installed, and then glue the PVC into the slip side of the adapter.
Be sure of what you're doing before you do it to the bulkhead. Home supply stores don't carry bulkheads - you have to get them from a LFS.
