What size and how many? I may have some around depending on size. If not most LFS stock some bulkheads and Elliotts hardware stocks very nice ones ( and charges like it ).
Er. . I don't know. I need I think it's called threaded/threaded and has to have the outside part has to be 1 3/4". It's for my 20g display tank's overflow.
you need to know what size you need and which side you want threaded etc. If you have a 13/4" inch opening I dont have a bulkhead that size here. Hopefully you found a LFS with a supply by now.
Yep, yep! Barry had an extra at his house when I went to pick up sand, yippie skippie. I have corals now too. This is exciting. I just need a skimmer now. Thanks a bunch everyone!
