If memory serves me correctly, high PH is lowered with Calcium Carbonate. You probably want to consult someone who is licensed in pool care, however.
It depends on the volume of your pool and what level your Ph is at.
The pH level in your pool may be consistently high due to factors such as high alkalinity, high calcium hardness, or the use of certain pool chemicals. It's important to regularly test and balance the pH levels in your pool to maintain water quality and prevent issues like scale formation and inefficient chlorine disinfection. Consider adjusting your pool water's alkalinity, using pH decreasers, or consulting a professional if the issue persists.
High pH
Honestly it depends on how high. An extremely alkali (high pH) pool can cause chemical burns with prolonged exposure. A pH of less than 10 is generally safe, though lower pH may cause discomfort in sensitive individuals after prolonged exposure.
High pH levels in a bromine pool can be harmful as it can reduce the effectiveness of the bromine sanitizer, leading to ineffective disinfection of the water. Additionally, high pH can cause skin and eye irritation in swimmers and promote the growth of algae in the pool. Regularly monitoring and adjusting the pH levels in a bromine pool is important to maintain water quality and keep swimmers safe.
High level of anything is not good for you. High pH level can be damaging for one health. I would advise you lower your pH until it reaches the right level.
i found out by my head
Your pool water turned green immediately after adding pH Plus because the chemical had increased the pH level to high. You may need to adjust the alkalinity levels of the water using another pool chemical such as pH Minus of pH Alkalinity Plus.
High Ph or high alkalinity in pool water makes the water "hard" and leads to "scaling" or calcium buildup on pool walls and equipment. Over a long period, alkaline water can be harmful to equipment and create a film of calcification on tile or pool walls. As far as harm to people, high Ph makes the water feel "slimey" and it is easier to slip on steps or the floor of the pool. It can dry out skin and feel ichy. In contrast to high acidity- high alkalinity seems to cause less skin discomfort. Each pool is an ecosystem and needs to find a balance...one person's pool could be in fine balance at 7.8 while another is better at 7.2
The proper pH level is around 7.4 to 7.6 If the pH is reading, 8 to 14 that would mean the pool has a high pH level. But if you have a low ph reading then your chlorine will dissipate quickly. To keep the swimmers in your pool comfortable and to keep your pool equipment in good shape, it is vital that the ph reading is balanced.
The pH level of a pool affects the alkalinity by influencing the stability of the pool water. When the pH level is too high or too low, it can lead to fluctuations in the alkalinity levels, making it harder to maintain a balanced pool environment. Keeping the pH level within the recommended range helps to stabilize the alkalinity, ensuring the pool water remains clear and safe for swimming.
You would be safest using Baquacil pH Increaser, which is a high purity, highly active dry alkaline product used to raise pool pH. In non-Baquacil pool water, both Soda Ash and Hydrochloric acid are used to raise pH levels. Pool shops are a good place to seek advice also.
