I'd be interested in know what Calcium is reading - some of the literature would indicate that it (chrystophytes) prefers low Ca.
Short term, however, I'd pull each and every rock and give them a good scrub down in old tank water - and you'll have plenty - I'd also do about a 50% water change at the same time.
