Enough ozone in the water does ... just like enough elemental chlorine is extremely dangerous and poisonous for all living organisms.
Problem is, the run of the mill ozone units sold for everyday water tank use risk getting enough water treated with enough ozone fast enough - plus there is maintenace associated with them that must be kept up with. I saved $1000 on up for a maybe marginal tank ozone system and have been going with good old chlorine instead. We don't get iron rings in the house, but our neighbor with an ozone system in his tank fed from the same well as us ... does. :h
