HELP! Need to identify this algae bloom before it kills all my corals.

That's exactly what happened to my frag tank. Got smothered by Dinos, after dosing Component 123 for about 3 months. I think its the accumulation of trace. I tore it down after loosing most of my SPS colonies. I restarted with the same Reef Salt but only dosing Kalk this time. Its been 3 months now, so far so good. I might go back to dosing bulk chemicals when dosing Kalk isn't enough.
