I can't remember if you have a glass or plexiglass sump, but, you don't want to silicone plexi to glass. Won't hold. Either glass to glass or acrylic to acrylic with weld-on glue.

Ya its a tuff tubs oval trough. Thanks though. I have a couple of people checking into some bulkheads. Going to wait and see if anything comes up. Heres hoping.

I got mine from a place here called Iritex. They have a web site, but they're only on the island if you can't find anything else.

Corix will have what you need and the sch 80 2 " bulkhead will work with that hole size.

If corix has any I can ship one out to you, shipping was cheaper than I thought on that skimmer so I can cover shipping

Hello. Thank you to everyone for the help. Someone locally dug out a used sump trough out for me. A little clean and I will be able to drill new holes. The right size this time. It's only a 110gal but that's ok. The price was right. Thanks again for all the help.
