I agree with Glen. My corals are similar to yours. In fact, they are in even worse condition. Mine will pale out within 3 weeks and lose pretty much all polyp extension. Eventually within 2 to 3 months, they will slowly STN. I have been running GFO and ROX very aggressively for 6 months and my tank would grow nothing but dino. There are virtually no pods, sponge, or various other filter feeders. There are no micro-funga even in the fuge. Despite phosphate has never measured 0.00 (from Hana Checker), there would be a thin green powdery film on the glass every 2 days.
About 2 to 3 weeks ago, I decided to take both GFO and ROX offline and the result has been very positive. The dino has all but gone. The powdery film on the glass has not returned. The sand is whiter. The pods and sponge are returning. The water remain as clear and phosphate remains to be 0.00. The macro and corallines are growing again. I fully expect typical hair algae to come next and The corals haven't showing much changes yet but I believe my tank is changing for the better.
Basically I put in extra effort to upset and hurt my corals prior to the changes I made. I am going back to where I have had success before this tank: Skimmer, fuge and water change. I am even going to stop kalk; just 2-parts. Just one less thing to worry about and one less failure point. I hope my corals will appreciate the changes.
Good luck!
(And yes this camera is definitely better than the one before)
