Why is my pH level always high in my pool?
An increase in the pH level can be caused by several things. A first cause is the addition of chlorine stabiliser or HTH Granular to the pool water. A higher pH level can also be caused by a sudden rise in temperature of the water. However, much more important than the causes are the effects of such a high pH level.
What causes the pH level to go up in a swimming pool?
Cause and effect of too high a pH level. An increase in the pH level can be caused by several things. A first cause is the addition of chlorine stabiliser or HTH Granular to the pool water. These strong chlorine products are the best disinfectants but they also result in a direct increase in the pH level.
Can a pool have a high alkalinity level?
Maybe yes, maybe no. Your pool water pH and alkalinity can affect disinfection by chlorine. Chlorine is very slow to react at high pH levels, and can be over 50% inactive at pH levels over 8.2. However, even with high pH a pool could still be sanitary with good levels of free chlorine, and clear water from effective filtration.
What happens if you put too much acidic water in your pool?
Acidic water can corrode your equipment, cause etching on your pool surfaces, and irritate your skin and eyes. But water that is too alkaline can cause scaling and cloudy water. Let’s take a closer look… Why should you lower your pool’s pH balance?
What happens to your body when your pH level is too high?
This in turn results in increased chlorine consumption. Also the physical consequences for swimmers are painful but easily identifiable. Red eyes, a dry skin and premature wear of swim gear such as goggles and swim wear are associated with too high a pH level.
What is the ideal pH for a pool?
The ideal swimming pool pH range is 7.4 to 7.6, with 7.5 being an ideal target pH value. Pool owners need to watch the pH level carefully, as too low or too high pH can cause significant damage to swimming pools.
What chemicals lower pH?
Consequently pool owners have to add pool acid to lower the pH. The chemical most often used is known as Dry Acid. Also called pH Minus or pH reducer the actual chemical name is Sodium Hydrogen Sulphate. Dry Acid is the preferred chemical because it is in dry, granular form.
What should pool pH be?
Most pool experts recommend a pool pH between 7.2 and 7.8. To raise or lower pH, a pool custodian simply adds acids or alkalis into the water.
What is the pH of a pool?
The ideal pH for a pool is between 7.2 and 7.4. This slightly basic pH level is perfect because it is as close as possible to the pH of the human body. With a pH of 7.2-7.4, pool water will have little effect on sensitive human parts like eyes, skin, and mucous membranes.
