BioGuard Spa Comfort Up raises the pH without increasing Total Alkalinity. Maintaining a correct pH will help to prevent scale build-up, corrosion of equipment, cloudy water and eye irritation.
Used in combination with Aquality, Performance Up and Shield to maintain correct water balance in your spa pool. Always adjust the Total Alkalinity before adjusting pH. If you are uncertain of how much to add contact the store for advice. It is always better to add slightly less than needed rather than too much as you can always add a second dose.
BioGuard Spa Comfort Up is used to adjust pH when needed with Perfect Balance.
Available as a 500g bottle.
