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.


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.
