The teeth look like they should be fine, but you'll never know until you fire up the system.

You should be fine with the 3x 3/4" lock-line. Have fun fitting those T's in there. I think that's the first overflow I've ever seen that was separated like that.

Yah, do to the positioning of the tank when I looked at it before buying it, I couldn't see the overflow. It wouldn't have been a deal breaker, but it definitely makes things more complicated...
 
Here's a little better drawing of what the setup will look like. Obviously I left the drains and sump innards unfinished, as I just wanted to show what I plant with the returns.

I will have 1x 1.5" pipe running from the pump up to the tank returns. The 1.5" pipe will be reduced to 3/4" right before the bulkheads. After passing through the 3 bulkheads, I will have a 3/4" lock-line adapter. Then will come a Y. Immediately after the Y will be the 3/4" spouts. So each 3/4" bulkhead will feed 2x 3/4 outlets.

I'm assuming the "lockline" you mentioned is a one way valve that will prevent the tank fron draining (via siphon) when the pump is turned off...

If so, I would still worry like he!! that the lockline would somewhow fail and the tank would drain. I know my canister return lines tend to grow algae inside of them and even a little algae at the lockline fitting could prevent a seal crom closing completely. I know it's a bit of a long shot but draining a tank on the living room floor is a lot to be risking...


But moving past that concern... and addressing your pipe size choices...

I think it's a good design...

Running the 1.5" diamter line vertically and all three horizontal lines at .75" will do a fairly decent job at distributing the flow. Naturally they won't be "equal" but I don't believe "equal": is your goal, as long as they are fairly balanced...

The lock-line is NOT a one way valve, it is simply a type of "tubing", see this website:

I will have a check valve on the 1.5" line inside the stand to prevent any water from draining back during a power outage or when pumps are turned off. I forgot to include that in the picture I drew up. Depending on how much they end up costing, I may consider putting two check valves on the line, just to have one as a redundant backup "just in case".

I had the very same thought about basically putting a drain a few inches off the bottom of a 220g tank... But I will make damn sure that there's no way water can drain back through the return lines and flood the room!
 
So I was thinking about plumbing part of the pump return to a rUGF. However, I'm planning on having sand in this tank for my stingrays. Will a rUGF work with sand, or will it be too strong/too much of a hassle to try?
 
You should think more towards an under gravel jet setup. That would work well.
 
I'm not a big fan of the under gravel jets, just because I worry about the rays running into them with their bellies. If it was fish only, this would be much easier...

Unfortunately I haven't gotten to do any work on the tank lately. I did get the sump, although I haven't installed any bulkheads or anything yet. I'm too busy working on my house trying to get it ready for sale...

I'm hoping to start working on it again soon though.
 
as long as t he jets arnt shooting sand or rocks. Rays like to play with bubble disc,i bet they would like the jets too.
 
Agreed, you shouldn't have to worry about hurting the rays on the jets. It should be fine.
