My advice would be, feedings(frozen/good quality food), water changes and
patience. I read parasites are always present, it takes fish weakness to
be vulnerable. I wouldn't try any medication again, especially on the
whole tank.

My newb thoughts exactly. I've had two minor bouts of ich both cleared
up with improved husbandry. ("Emergency" Water changes - turn over at
least 50% of the tank in a day or two.)

A celaner shrimp may help. Mine used to jump on top of the fish to clean

The first time my tank got ich I ran out and got a cleaner. He got busy
quick and it's fun to watch him now. A great addition to a reef tank in
any case.

The other other thing I did was feed flake soaked in fresh mashed
garlic. I was surprised everyone ate it, but they did. The ich cleared
up in a few days but more importantly did not come back.
