I have it fairly high up but off to the side. I have a lot of other SPS that are growing at a brisk rate so it's not a tank issue. I've seen a bunch of Blue Iris pics but never seen brown hairy polyps with them. I'm not convinced you have Blue Iris just by growth rate alone. A lot of people on Reefcentral also report bonsai growth rate with them. There are other ORA corals that are teal/blue with brown polyps like Joe The Coral. Unfortunately, a lot of ORA corals have very similar colors. Look up the ORA site for a complete listing and pics of all their corals. If you have brown polyp, it's not Oregon tort or Blue Iris....mine is all blue.
