My colors are starting to come back!
I've added some sand and a whack of new fish and feed them 3 times a day (added fish include 6 green chromis and a yellow tang). I've also been able to stop dosing Zeovit additives. Additional changes have included: removing the filter sock and performing weekly 5 gallon water changes (previously bi-weekly).
I still have some corals with significant bleaching on the upper portions of branches but I'm hopeful that based on the recovery so far those corals will recover over the next couple weeks.
