Relapse... Saltwater again!!! Need some advise on Drilling|Bulkheads|Sump|Return Pump

[KidFrost]

Hello all,
I am having a relapse, I was out of fish tanks for a while because I moved from college... a few weeks ago I decided .. on a whim.. to drive to Petco.. JUST TO LOOK!! a few hours and a few hundred dollars later I was sitting at home trying to put my stand together for my new 75 Gallon tank..
Currently it is setup fresh water and I have about 10 Mbuna African Cichlids... So far so good not to involved..

During a trip for work I had to go back to Williamsport PA .. where I went to college.. and I decided to stop at the fish store that enabled me to start up my first SW tank.. well a few long minutes later, after starring at the display tank, I decided I had the itch again..

This time I own my own home and I have a little more room to work with thus more options. Not to mention a little more mature and paitent.. So I am looking ahead and this time I want to plumb a sump in my basement. I also want to drill my tank for a stand pipe overflow, and also for a return.

I am thinking an old 55 gallon tank will be plenty sump for 75 gallon display tank ..

Enough babble .. on to my questions..

What size hole do I have to drill for a 1.5" bulk head?

What size return line/bulkhead should I run if I run a 1.5" stand tube?

What kind/size/brand of pump should I use to return water from my basement?

Thats all I can think of at the moment..

Thanks in advance for any info/ insight...

P.S. Some pics of my old setup.. Oh I also still have that wet/dry that I plan on running in the drain line before my sump..

What physical hole size is needed for a bulkhead?

thank you for the links... very helpful.

And This is not my current setup.. I had this 2 years ago and I want to set another SW tank up.

So after some digging in the garage heres what I found.






Most of my old equipment.
Mega Flow Wet Dry
Protien Skimmer
4- power heads.. 3 Rio 1100.. one smaller one..
SW alkalinity tester

Threw the pumps in the tub and made sure they all work.. now I have to lug the 55 gallon tank back to my house and start fabbing.
