If your tanks only been up for a week, those coral and CUC were nothing more than a waste of money. The fish you had that have already died are proof of that. IMO
, the bacteria in a bottle is nothing more than a waste of money as well. Sure, it may speed up the cycle, but not make it all set in a week, especially for corals. If I were you, I'd return the fish and coral and cleaner shrimp. Snails and hermits MIGHT be ok, but that's a lot of stress for them with the param spikes
But it appears you don't really want to do it right and take your time if you've already been informed, so I hope I'm not wasting my time.
