How many of you sps guys toss your dead skeletons once your coral dies? I've done it but that last time I had issues I just left them be unless. 6 months later and some times longer now I am finding those coral skeletons coming back to life. They would be so dead that they where gray and all of a sudden there is polyps again. So for those of you who lose a sps colony sometimes there is still hope.
