dlleno Posted August 28, 2017 Report Share Posted August 28, 2017 I can vouch the the multiple purge recommendation. I have personally coached others through as many as 10 ahh some purges. It takes patience and the understanding that stuff hides in the pipes and can take several tries to get it. I'm always astonished at the accusation that ahh some itself contributes contaminants just for the impressive visual impact. After correcting the issues of biofilm in my own spa I was able to achieve an ahh some dosed vessel, with filters installed, releasing no new material. That's a clean spa!
