What is a good sump for my Fluval Flex 32.5g?

[ASWoodsy]

As the title states, I have a Fluval 32.5, but I soon plan to redo it. I am going to modify it by taking of the AIO system and putting a sump underneath, but I do not know which overflow to go with. I chose the XAqua InOut Overflow, but after more research, I am unsure if it is the right one to go with or if I should get a sump that runs as a Herbie Overflow. If there is any other tips that anyone has, I am fairly knew with sumps, so it will help!

Is there a reason why you want to remove the AIO sump? You could just upgrade the pump and media basket instead.

I’m looking to widen my knowledge on reef tanks, and I plan to have a refugium.

Hello, I have a Fluval Flex 32 with a Fiji Cube 12 sump. I added a Fiji sump on May 28th. I attached pics of the sump and a current picture of my tank. I am now working on converting my Flex 15 into a salt water tank!

What did you use for overflow?
Thanks
