What are you testing ammonia with? A 1 bottle test kit or 2 bottle
salicylate based ammonia test? If only 1 bottle, that is why you're showing
ammonia, if 2 bottle, and you're still getting ammonia readings, add more
Ammo-lock, or the other brands RTB mentioned.

Before all this happened, there were 17
goldfish in there, and the water chemistry was perfect.

17 goldfish in approximately 275 gallons (assuming you didn't fill to the
rim?) I'd say they were over crowded. Even in the best conditions it is
recommended to give goldfish 20 gallons/fish. More if you want them to grow
well.

Aeromonas hydrophilia is a 2ndary infection, and the stress of over
crowding can weaken the immune system. Did the fish specialist do a scrape
and scope to see if any parasites were involved? The salt, if added over
several days to get to 0.3% shouldn't have killed the filter, nor should
have the antibiotic food.

Koizyme works really well on lowing the Aeromonas and Pseudomonas bacteria
in the water column, but it is important that the fish have a good immune
system to also fight those buggers off. ~ jan
