Can I add a water fragrance to the spas water with Spa Alchemy water treatment?
Certain foreign chemicals may adversely affect the balance of the water so it is best to use natural fragrances. 


Why did my water lose clarity when I dosed it with Spa Alchemy water treatment?
When dosing your spa with Spa Alchemy, you may find your water gets slightly cloudy or foams up in some cases. This is Spa Alchemy removing all the hidden contaminants from your water, pipes and filters and should clear up within 3 days. If problem persists, please contact your retailer for further advice.

What should I do if my spa water becomes less clear?
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 should also help remove contaminants from your water and speed up the process.

As every spa and it's usage can differ, regular testing of your spa's water balance is important. 

Additional tips for best results

Regularly clean the filters thoroughly with a filter cleaner and rinse well to remove any residue. You could also use some pipe and surface cleaner to clean the inside surfaces and pipes of your spa. A drain and refill after thorough cleaning will also reset your spa water chemistry and allow Spa Alchemy water treatment to do its job better. Refer to Start Up Procedure under Directions for details instructions.
