I think I have some 1" slip bulkheads that came with one of our Oceanic sumps - I will just insert the pipe into the bulkhead, so I can remove it later if needed... I plan to have the pipe extend far enough into the tank so it won't be noisy (splish splash) when circulating the saltwater...
Thanks for all the help!

In our salt mixing tank we have it centered so it moves the salt around, I think Ed used (2) 45 in different directions if that makes since...... in the beginning we had the pipe straight down and all the salt seemed settled in the middle.. This way it moves the salt around the tank.
In the fresh water tank the pipe goes all the way to the bottom as well, because we use that side for the ATO.....
Have you decided if you are going to use an ATO or not???
I think now is a good time to decide......

The two 45's makes sense. How far into the tank did Ed run his pipe before adding the 45s? Near top? Half way? near bottom? Based on my SW mixing, I think a foot or so above the bottom would make sense...

The first piece of pipe is very short. Then I used a true union. The union can be purchased at Lowes/Homedepot. It is a threaded connection that allows me to remove the pipe for changes and modification - no cutting.... After the union I used a second very short pipe then two 45's to get to the center of the tank and perfectly vertical. I terminated the pipe to within two inches on the bottom of the tank. I discovered that I eliminated the dead spots and noise. The water boils and mixes much better than returning the water to the top of the water column....

So I want the pipe for SW mixing near the bottom, in the center? That's close to the pump intake...I figured it should be a little further away...but I guess not. I'll have to get an extra double union... Do I want to configure the RO/DI ank in the same way, or doesn't it matter?
I already have two double unions, (7) double union valves and the necessary adapters to go from bulkhead to slip fittings... As soon as I get all the fish and coral transferred this weekend, I am going to tackle the water change system!
Answer:
YES!, near the bottom and centered in the SW tank.
You are correct they are close together. The biggest problem we were attempting to resolve was the settling of salt on the bottom.
This design eliminated the problem. We added a medium sized Korilla pump (magnet on the out side of the tank) to increase the water mix process. The Korilla allows you the ability to locate it any where with no plumbing or hardware...It is located mid level and pointed upward - we found this the best setup as it stirred the upper water column and boiled the surface.
I did not use a true union VALVE - just a union coupler. Same part minus the valve- shorter in length and I did not need the valve....
On the RO/DI tank I have two pipes. The first pipe is in the bulkhead and goes to the bottom. On the bottom I tie strapped the ATO sensor (low water sensor). On the out side of the tank on the other side of the bulkhead I put a 3" pipe and a cap. Then
I drilled a hole for the RO fill line.
On a second pipe I ran it to the bottom (1/2" pipe) - I connected a small pump used for the ATO system (tie strapped the cord to the pipe). I did not use a bulk head fitting as it is near the top of the tank and the water is pumped up... Again I highly recommend a union adapter to allow removal to maintain/replace the ATO pump and ATO sensor. The RO/DI tank has a small hole on the side for the RO float sensor.
The water change system will be a piece of cake to assemble compared to the CL system you just connected with NO LEAKS I might add...
