I've got the set up: lights and eflux on my 125. Not the dc pump as it was too large for my sump space. I actually have the 2100's and run them only at about 30 or 40 %. I have them on the sides, by the back, pointing toward the front glass. I have a 3rd jebao wavemaker in there, just to the inside of one overflow box, pointing to the opposite side glass. It's also turned down. I plan to get 1 more eflux, for the same spot on the back wall. I'd rather have more flow, have the flow turned down, then be running them full out. This way I can adjust and go stronger if I need.
So far I love the eflux--quiet. Tank was just started (filled with water) in Feb. and has cycled and starting the uglies. Bought the 2 eflux, 1 with the kit, 1 single. A few weeks later, got the lights with the loop. Only thing, I may, or should ask for another hub to have on hand as the one for the lights is sometimes flakey but if not touched it is okay. I think they'd have to send the entire hub unit for both as they are mounted together. But other than that, everything works nicely.
The loop is great. Took me a bit to figure out the lighting and programming. Easy to run and set the eflux. I have 2 of the marine orbit ic pro's with their brackets. Very pleased so far with what I purchased. First batch of corals in qt, along with fish in another qt. Eager to get them all into their new home!
