Your tiny alk change did not cause a mass stress event.How did your sps look before you turned on the gfo?
My corals were doing just fine with the 1 tbsp of gfo. This was approx 10 days before the water change event, and 2 days after the water change I had my first casualty with the strawberry shortcake RTN. That day I did panic and thought the elevated phosphates killed the acro, so I added a 2nd tablespoon of gfo into the system.
