Everything seems to be dying!

I had my Tunze pump fry in tank and next day seems like all my corals dying. Could it be something like metal contaminated tank? I am doing an emergency water change as we speak.

I tested my Alk and its at 6.1; I am going to retest again using salifert. I added some soda ash and will recheck my alk.

Whats crazy also my aiptasia that I had in tank seems like it disappeared as well. I am lost why my alkalinity dropped so fast if thats accurate. I think it's more than alkalinity though. Seems like my soft corals melting..
