Overflow Pipe VS. Return Pipe (Bulkheads)

[Blaque Kuchel]

I currently have a 90g Tank that I bought used and set up. All of the hard plumbing came with the tank so it was ready to go. I want to revamp all of the life support system on the tank to include all of the hard plumbing.

I am looking for a 1" in bulkhead with 3/4 center that is slip x slip or thread x thread. Do they make something like this ? If so can someone send me a link to buy some?

They make every combination there is. Check Bulk Reef Supply in the plumbing aisle.

Edit: every combination of fitting types. You will need a bushing to step down from 1" to 3/4" using a 1" bulkhead.

Thanks I appreciate it. I am putting the Aqueon mega flow kit on my tank but the tank was custom drilled with holes for 1" bulkheads
