IMO, your dealing with an external parasite compounded by poor water quality. here's a play-by-play...your bacterial bloom creates a water quality issue that attacks the protective slime fish rely on to resist parasitic infection. once the slime is reduced to an ineffective state, parasites take advantage of the situation, and attack the fish. if your water quality is 'less than ideal', the wound created by the parasite cannot heal properly, and becomes infected. the end result is a fluffy looking fungal infection.
you need to give the tank a 50% water change, introduce salt (1 tbsn/5gal) to assist with battling infection, and then watch and see. after a week, you should see the damage start to rescale. if you do not..then up the salt another 50% for another week. once the healing shows to be effective (scales become smooth again), then you can start to relieve the salt dose, with biweekly 30% water changes.
don't blame your self...this happens with plenty of new tanks that have excess substrate and 'airy rock work' like yours. your only trouble was the bac cloud. once you break past that point of new establishment, reoccurance will be minimal. HTH.
