aquarium bulkhead
Aquarium plumbing questions, accessories partition?

I currently have a facility overflow box as part of my project but I need know what size i need for the locking system. The holes in the overflow box are 32mm big, so close it, I need size? I looked A bulkhead 32 mm, but the '32mm "seemed to be for the tubes, but the hole is adjusted, in fact, said in the description that" requires atleast a hole 42mm. If anyone knows how to close the scale needed help, if you get me a link to a shopping site in the UK gets the 10 points best answer …. First come, first served! Thanks in advance: D

Finding the right size of the bulk head is a pain. I know this is not the best answer is if I had to do was take a piece of paper, put it against the hole, the shade with a pencil so you have the exact size of the hole and go to a store specializing in saltwater and match with adequate bulk heads. A little secret, most people only get PVC fittings with some neoprene on the inside of the tank and adjust these. I personally have bulkheads most of my tanks, although I'm drilling a lot more of them soon and I'll go w / PVC Fittings-strengthened glass with some neoprene or other material washer inside.
