Actually, Oz, an increase in slimecoat like OP describes is often caused
by protozoan infections rather than bacterial. Chilodonella causes
excessive mucus production, clamped fins, and lethargy with no visible
spots. It's treated like ich with salt baths at 2-4 tbsp/gallon outside
the tank or formalin/malachite green.

There's a bit of info on it here.

It could be a few things as you've noticed.
