Yes I did. But I only buy sick cheap corals. All those plates you see were cheap because they were showing skeleton and no colour . In the tank good stable parameters and most of all seachem trace & plus each twice a week ! Saw double extension on all corals after switching from Red Sea energy to seachem. & considerable drop in phos & wallet ! Took about. 6 weeks after stopping energy to see a noticeable difference in all corals including BTAs
