Calcium Flakes sounds a bit like a breakfast cereal, but you wouldn’t want to eat them! The appearance of calcium flakes on the spa floor in a residential pool and spa combo with a saltwater chlorine generator can be attributed to several reasons:
1. High Calcium Hardness: Saltwater chlorine generators can increase the calcium hardness level in the water over time. If the calcium hardness is too high, the excess calcium can precipitate and form flakes that settle on the spa floor.
2. High pH Levels: If the pH levels in the water are too high, it can lead to the formation of calcium flakes. High pH can cause the calcium in the water to become less soluble and form visible flakes.
3. Imbalanced Water Chemistry: An imbalance in water chemistry, such as a high total alkalinity or high levels of minerals, can contribute to the formation of calcium flakes. It is important to regularly test and balance the water chemistry to prevent such issues.
4. Hard Water: If the water source for the pool and spa combo has a high mineral content, it can lead to the formation of calcium flakes. Hard water usually contains higher levels of calcium and other minerals, which can result in scale deposits.
To address the issue of calcium flakes appearing on the spa floor, it is important to maintain proper water chemistry and address any imbalances promptly. Regularly monitor and adjust the calcium hardness, pH, and total alkalinity levels according to the manufacturer’s recommendations.
Additionally, using a sequestering agent or scale inhibitor can help prevent the precipitation of minerals and reduce the formation of calcium flakes.
