Our illustrious health department has decided we must have automatic chemical controllers on all public spas. To date this has not been a large issue as most public spas are reasonably large say 10 000 litres and relatively calm compared to private spas. However now the word is all and this includes tiny portable type spas as well.
The problem with these tiny portable spas is the aeration is so violent and so intense it saturates the water with air creating a white water (so much air in it) which drives the pH up.
This is driving my ORP/pH controller nuts. Anyone encountered and solved this issue before?
