Oh..that's too low for a reef. Could already be a shock to the corals, maybe the bio-filter. Bring it back up really slow, I would start asap. Sorry to hear this, I feel for ya bro, looks like no sleep for you tonight. I would get some water/salt on-hand in case of a mini cycle kicking off.
Cheers,
