Nice going Kev. The tank is looking very healthy. I agree with RN, hold off adding more bioload until your happy with the levels you are getting. I just got stung by a bad ElOS PO4 kit. My phosphates got all the way up to .25 and I just realized it a week ago. I don't know how long it was up that high. I couldn't understand why I was losing my caps and other corals were bleaching from the tips. I purchased a Hanna Photometer and I'm down to .013 within a week of finding out. Hopefully things stabilize soon. Not a good feeling. Wish me luck!
