Most soft corals and LPS thrive in high nutrient water.
As for your problems, I'd bet the farm you removed the PO4 to quickly. You need to bring it down at a moderate pace. Once you get it down, DO NOT let the GFO get exhausted before replacing it, it is better to replace the media sooner than later as if your PO4 starts to rise before you change the GFO, it will only strip it out quickly, again repeating the same results you just had.
