As Spa Alchemy™ water treatment initially starts to work, it can take up to 3 days to clear up your water, pipes and spa surfaces of hidden contaminants.
However if your spa has heavy usage, long exposure to direct sunlight, is contaminated with lotions or creams, or has any sign of decreased water clarity for longer than 3 days, shock dosing with chlorine or equivalent sanitiser should help.
Thoroughly cleaning your filters more frequently will also help remove contaminants from your water and speed up the process.
As every spa and its usage is different, regular testing of your spa’s water balance is important.
