Treatment of Marine ICH or White Spot or Cryptocaryon in reef aquarium

YouTube video (by Gerald Bassleer) explaining diagnosis, life cycle, and multi-pronged treatment of marine Ich (Cryptocaryon) in reef aquaria. Shows affected fish (surgeonfish, butterfly), describes how parasites live under fish mucus and reinfect after leaving the host, and recommends combined actions: raise temperature (to 27°C), daily siphoning of substrate and visible parasites, continuous lighting to prevent nocturnal reproduction, UV/ozone and microfiltration (filter size cited ~<300 μm) to remove/kill free-swimming stages, and safe reef medication (Protomor) used alongside biofish food Metrine (presented as a repellent/immune-support feed) for about seven days. Also advises removing carbon filtration and possibly disabling the skimmer during medication.
