Hi Don, I agree with your advice, especially the need for a full risk assessment and monitoring program. My only added suggestion in the case of removing existing scale that other forms of descalers be trialed rather than acids. I believe there are far safer and less toxic ways of managing scale. If you are interested in learning more about the non-toxic, non-corrosive and bio-degradable descaler my company has developed and manufactures, please email me at andrew@waterandoilsolutions.com.au
