Adding bigger sump to my Fluval M90

[WIReefer]

Just wanted to let you guys know what I've been up to lately so I'm currently working on a DIY sump for my Fluval M90 tank I wanted to share my project and wanted to add a little more water volume and I also think behind the scenes of a tank is a really cool part of this hobby and wanted to make mine better. I was also wondering if anyone has the same tank as me and has done this? I plan on making shelfs for the sump with egg crate, upgraded to a tunze skimmer, going to add carbon and a little something else to the sump. Just was wondering what everyone thinks of this and what I could do to make it better. Thanks for looking guys!

Nice. I was wondering if that drain would be enough flow for a sump as I was researching AIOs. You would say it is?
