IM 25g lagoon EXT plumbing

[Smiley28]

I know a lot of people are fond of the aio 25g lagoon but I'm having trouble finding information or examples of plumbing on the 25g EXT. I haven't found much in general on the 25g EXT so I thought maybe some fellow reefers could share plumbing setups and info for the EXT and maybe some suggestions and tips? Pictures of plumbing would also be greatly appreciated.
