Yea. With so many variables it’s hard to diagnose.Just wondering if I should do any water changes or wait and see. Gonna go through water tests again tonight and see if anything has changed but few frags have gone pale/white or are gonners at this point so not sure what went so way off course. All my testing hasn’t shown anything extremely drastic and the fact that not everything has reacted the same way has me Scratching my head.
But if you mainly suspect nutrients as the cause of paling then I’d skip water changes.
Fwiw , I’ve had a tank of corals when half died or nearly died and thonothers we’re fine even had it happen when one half were sps dying and the others were sps too. Even acros. So that’s common.
