I was going to do a water test today on my new tank but realized the bulkheads were in need of being replaced.
The holes I believe are 1 1/2 inch holes in diameter. Does that mean that I need to get a 1 1/2 inch bulkhead?
Also what are your recommendations: should I get both sides threaded or both slip or one slip and one threaded (AAAGGGHHHHHH).
Last question, the man I bought the setup from had siliconed the bulkheads in place. BUT I read on RC that this was a bad idea. Is it? What should I do?
