Spurring growth after stress

As I mentioned in my other threads, I had been battling high phosphates earlier in the year and only reaching some sense of stability in the past month or two. It'd been a while since I'd stressed my corals out this much, so I'm curious what people think in terms of reinvigorating growth. Do people believe in pruning dead heads (e.g. torches) or fragging at all to incite regrowth?
