We have recently started using this process in our water systems in a healthcare environment. We are already noticing the porcelain toilet basins are discolouring to grey for some reason after onLY 4 weeks. other items - basins baths - are not affectedThe water appears clear and fit for use but the discolouration is alarming. Has anyone else experienced this and if so come up with a remedial answer.
