Alk Up - 750g

Spa Pure Alk Up is designed to increase alkalinity and can help prevent problems by stabilizing the spa pH and ensuring that your spa is safe for relaxing. More importantly, maintaining a balanced pH by effectively administering an alkalinity increaser also ensures that your spa water is refreshing and enjoyable. Essentially, alkalinity increaser acts as a buffer and improves the ability of your spa water to resist pH changes. When your alkalinity level drops below 80ppm, pH will begin to fluctuate dangerously causing water to become acidic and corrosive.
