In The Swim Solvay Bicar Sodium Bicarbonate Alkalinity Up, 50 lbs.

Striking the proper pH balance in your pool water is critical for safe and enjoyable swimming which is why many pool owners may find the need to use an alk increaser from time to time. Generally speaking, you'll need to increase pool alk whenever the pH drops below 7.4 or when alk levels drop below 80ppm. Ideally, you'll always want alk to range between 80 and 120ppm and should you dip below this you'll need to use a pool alk increaser. When alk is too high, your pool water is equally unsafe and scales will begin to form on your pool and pool equipment. Granular alk increaser can help to prevent these problems by stabilizing the pool pH and ensuring that your pool is safe for swimming. More importantly, maintaining a balanced pH by effectively administering an alk increaser also ensures that your pool water is refreshing and enjoyable on even the hottest summer day. The vast majority of alk increaser products are made from sodium bicarbonate which is a safe substance. Depending on the size of your pool you will need to carefully measure your alk increaser in order to accurately and effectively increase pool alk. Essentially, alk increaser acts as a buffer and improves the ability of your pool water to resist pH changes. When your alk level drops below 80ppm, pH will begin to fluctuate dangerously causing water to become acidic and corrosive.
