Also a 900 owner with a newer build going. Interested in seeing what others are doing with the same tank and sump layout. FWIW I will be making my secondary sump a frag tank with a fuge in the front main chamber. Have AI lights in both for their respective purposes. Not a lot of water movement as I’m sure you both have noticed. I added a smallish pump to hopefully move more water through the secondary sump.Follow along. I have had my RS 900 up and running for a few months and noticed your build thread. Did you use the secondary sump/sump extension?
