What corals are reaching? I don't see it so really am curious what you're seeing.Personally in this case, I would do a rip clean on it, and then build it back up properly.
I would add more rock, and definately needs a powerhead in there.
I would remove the macro algae from the tank (make a decision, corals or macro algae).
Some of the corals are reaching for light, so I question the lighting.
How often do you do water changes?
Also not familiar with a rip clean...
