Help Please

I've had a 65 gallon reef now for about 2 years. I thought I had a grasp on it because everything has lived for a year or so until now. All my corals are struggling and I've already lost my bubble and colt corals. My shrimp and starfish have perished as well. All my fish are doing fine though. I've tested the water and brougth some to my local fish store and we both agree everything is fine. I've changed 30 % of the water three times in the last week and a half. Any suggestions of what may be wrong. Thank you!

buy a copper stest kit.
Also what kind of lighting are you running?

A lot of times tap water will have copper andother things in it that is harmful to inverts. If your using tap water, Id suggest using ro/di water instead. Do a few water changes with the ro/di.
