Why did our pool water and everything in the turn a deep turquoise color after adding Balance Pac 100 to raise alkalinity.?

Balance Pac 100 does not contain any ingredients that would directly cause pool water to turn a deep turquoise color. The coloration is likely due to a chemical reaction between the product's ingredients and other substances present in your pool water. Here are a few possible explanations:

- High pH levels: Adding Balance Pac 100 can raise the pH level of pool water, making it more alkaline. High pH can cause copper plumbing or metal components in the pool to corrode, releasing copper ions into the water, which can produce a turquoise discoloration.

- Reaction with chlorine: Balance Pac 100 contains sodium bicarbonate, which can react with chlorine in pool water to form trichloroisocyanuric acid (TCA), a compound that can impart a turquoise hue.

- Presence of metals: If there are significant amounts of dissolved metals, such as copper or iron, in the pool water, they may react with Balance Pac 100's ingredients, resulting in a turquoise discoloration.

- Unusual water chemistry: Certain impurities or unique chemical compositions in your pool water could interact with Balance Pac 100, leading to the observed color change.
