Okay so it looks like your tank is set up for dual durso drains. Is this something you wanted to keep? Or did you want to step into a different style of drain with a little more redundancy?

The photos clearly show 2 different size bulkheads.I used 4 1 in bulkheads from BRS, same overflows as u have pictured
I have never seen bulkheads at home Depot or Lowes. I saw some at Orchard Supply recently. Your LFS should have them or you can order online. What size are the bottom of your tubes? They look like 1" & 3/4". Then measure the holes in the tank.
Yes, looks like 1 1 in and 1 3/4 x2, Mine were both drilled to 1 in and therefore I was able to use 1 in bulkheads x4, I was just showing what I did on the duals for my tank, she can purchase 2 1 in and 2 3/4 bulkheads and have then installed in a couple of minutesThe photos clearly show 2 different size bulkheads.
Lfs is an hour n half away. Maybe they will be open tomorrow. I’m not going to bother going to either lowes or Home Depot then. Maybe Ace hardware. If not I guess I’ll have to go to Houston. I’ve got some old ones that were given to me if I can find them. They might be ok to use just for the water test in the garage
Great, just make sure the gaskets r in good shape before u install themFound the bottoms of the bulkheads. He had put them in a bag with the screws for the panels that go on the stand! Yay!!
Here's a link to Eshopps' "how to drill a tank" video.I’ve got a used dual overflow 150 gal. No manual lol
I hear ya.
Many became a better reefer after they did just dropped in for a hour or so.
