Is this the dreaded Ich?

My local LFS advised me to medicate the tank with 'Anti-Ulcer & Fin Rot' by NT Labs. I added the quantity in the instructions, noting that it was harmless to fish and plants, and within 48 hours half my tank was wiped out! 10 dead mbuna. Absolutely heartbreaking. Things in the tank have now stabilised after several large water changes.
Meanwhile, the efasciatus is still swimming around. The white nodules seem to have shredded and look more like ulcers - possibly he's been rubbing himself against rocks?
