Advice on plumbing a new sump needed.

[eses]

I am setting up a new sump for my 75G, space in my stand is making me have to get creative with things. I have a 20 gallon acrylic that I was going to use, but I also want to use a taller tank in conjunction with it to increase water volume. The taller tank is going to be acrylic as well.

I need to put a bulkhead in the taller "feed" sump, and run a line from it to the lower one. I have no experience with bulkheads, fittings, or plastic-plumbing. Looking at marine-depot, I see "Double Threaded Bulkhead Fitting", "Double Slip Bulkhead Fitting", and "Standard Threaded Bulkhead Fitting (Threaded x Slip)."

I would like to run a PVC flex-line from the bulkhead to the lower tank. Which of these style of bulkheads are easiest to use, install, and plumb to flexline?

Or if you have a suggestion on a easier way to do this, any comments would be great. I've attached an image of basically what I'm talking about to help explain what I'm talking about.

Thanks

just make sure you have some sort of safety with that. the one line could get clogged and overflow. be safe make two lines.

I planned for two lines...but unfortunatly I didn't think far enough ahead, I put the 20 gallon sump down into the stand today and realized I don't have nearly enough room to run two seperate water containers...so much for that idea. I forgot the joys of setting up a new tank from scratch.
