Considering my options on filtering this 1500 gallon. Not sure if I should do a regular sump on the side of it or overhead sump. What’s some pros and cons to each? It will have large BD stingrays in it.

I don't care what you do as long as you post pics!
Consider a close loop system. Biggest Ultima you can fit stuffed with k1 micro
I’ve never personally used it but I’ve seen some canister type looking water polisher in a long cylindrical tube. I think Pacu Mom maybe JK47 or someone else used that’s specifically for mechanical filtration purposes. I also believe K1 micro due to the size will trap many particles but requires more backwashing. Could be wrong! ??

If perfectly clear water is what you are after put a DE pool filter (Hayward EC-40 should be plenty big enough) in line after the Ultima. You will not get clearer water with any other setup. You could keep the filtration closed loop with this configuration if you wanted to.
A sump is nice for oxygenating the water and off gazing which a closed loop system doesn't account for. If you have other means for an air/water interface a closed loop system should be less hassle than a sump.
P.S.
With a sump below the tank water level the water level in the sump will go down due to evaporation.
With a sump above the water level the tank water level will go down with evaporation.
Above water level sump - Your auto top off float valve will have to go in the tank.

I really like Pentair Rainbow RTL filters for mechanical filtration. RTL filters are spa filters and are used on large reef tanks for mechanical filtration. I was clueless when setting up our 300 gallon tank and consulted with a man who sets up and maintains salt water tanks for businesses. He sold us our first RTL filters along with a ReeFlo Hammerhead pump. The only other MFK members (that I know of) using RTL filters are Oftalmos on his 765 gallon tank.I’ve never personally used it but I’ve seen some canister type looking water polisher in a long cylindrical tube.

My 765 gal tank...Part 1...
Hi to everyonebefore I start writing about my tank I just want to say that I dont speak or write perfect English... so I apologize if you see bad spelling. I want to start this article saying that for me was a marathon to make this tank work, it took me more than one year to finish it...

jsc incorporated an RTL filter in his build and really likes it.

I've had this tank for a while. It's been at 3 different houses and always been on 2x4 stands. I wanted to have more of a finished look. I started with the stand

Unfortunately, family illness and multiple surgeries for me (including another surgery yesterday) has derailed my working on our big tank. On our small 300 gallon tank we are running two RTL-25s with a ReeFlo Hammerhead pump for extreme mechanical filtration. The big pump with a Venturi return nozzle (another spa part) creates a strong current in the tank which our fish love. In addition, the system spits out a lot of air so we don't need any other form of aerators. The beauty of the venturi nozzle besides enhancing the flow, is that the flow can be directed wherever you want it to go.
I love the RTLs so much, I'll be going with six RTL-100s on the big tank for mechanical filtration. The two Ultima II 4000s will be used for primary biological filtration. One of the Ultimas will be used to return the water from the sump back to the main tank. The sump is for redundant filtration. Such big plans, too broken down to work in the tank.
