Everything is good. I have had the sump and skimmer set up for about 8 weeks. They're working great. I originally set up a turboflotor skimmer, but it didn't work very well. I went back to my old super skimmer and its working very well. The sump took a little while to get dialed in but is working great. (I think my tank is going thru a mini cycle because I just had a diatom bloom- it's going away tho) I don't have any hob filters anymore. I had a mag 350 canister and a nice fluidized bed filter. I've removed those since my sump is running.
Flow- I have 2 1400's and 3 different size aqua clear power heads. My tank was originally set up for fowlr, but I taken the plunge and purchased a handful of frags. They're doing well. I just upgraded from compacts to t5
