Umm Think its more about placment of the corals and what type of LPS ... and location of powerheads. I currently only have a kolia nano and a mj900 and my return from a rio26HF pointed at the front corners and does great, 2 dead spots where food collects but anemone likes one spot and the other I keep a short tentacle and tongue coral.
