What do I do if my pool pH is low?

What do I do if my pool pH is low?

If your pool’s pH tested below 7.2, add 3-4 pounds of baking soda. If you’re new to adding pool chemicals, start by adding only one-half or three-fourths of the recommended amount. After retesting, you can always add more if the level is still low.

What happens to chlorine if pH is low?

pH affects chlorine levels when it is too high or too low. When the pH level is too low, chlorine is actually cleaning more thoroughly, but the pool water becomes corrosive. It can also damage pool liners, pool pumps, pipes, and other components of the pool.

How do I control the pH in my pool?

To lower the pH, the most common liquid acid used is muriatic acid, also known as hydrochloric acid. To raise the pH, soda ash (sodium carbonate) is normally used. Sodium bicarbonate (baking soda) can be used to raise pH if the alkalinity is low, but it’s more commonly used to raise alkalinity.

Will Shocking a pool raise the pH?

When you shock a pool, you test and adjust the pH level for a reason. With that said, if you shock a pool outside of the 7.2 to 7.4 pH range, not only will you waste a significant amount of the chlorine used, you will also end up with cloudy water.

Will chlorine work if pH is too low?

Chlorine levels and pH level are the two most important chemical balances to maintain in a swimming pool, and pH affects chlorine levels, especially when it’s too high. When the pH level is too low, chlorine actually sanitizes more efficiently, but the pool water becomes corrosive.

Does chlorine affect pool pH?

Pool Chemicals The chemicals used to sanitize the pool also affect the pH of the water. Granulated or liquid chlorine is alkaline and, therefore, tends to raise the pH level. Bromine is more neutral and has a minimal effect on pH, while chlorine gas is acidic and lowers pH.

Why is the pH in my pool low?

In most cases, low pH levels are caused by natural factors like a heavy rainstorm, overuse, and improper use of chemicals. A substantial amount of rainfall can alter the pH of pool water to become more acidic. pH levels might also be low after a large party.

Does too much chlorine raise pH?

Using liquid chlorine raises the pH of the water. Liquid chlorine does not raise pH. When added to water, liquid chlorine (which has a pH of 13) makes HOCl (hypochlorous acid – the killing form of chlorine) and NaOH (sodium hydroxide), which raises pH. So the net effect on pH is zero (or almost zero).

What should the pH level be in a swimming pool?

When your swimming pool pH level is 5.5, the pool chlorine is 100% effective. At around 7.2-7.4 the chlorine is about 50% effective.

What’s the relationship between pool chlorine and pH?

Although chlorine is the single most important component in terms of taking care of your pool, it is not independent from the other components of your pool water. The degree to which chlorine is effective in sanitizing your pool by breaking down contaminants is highly correlated to the degree to which pH is kept in balance.

What causes the pH in a pool to drift up?

pH drift is common and is due to a number of factors impacting the pool water. Salt water systems are one of the biggest reason for pH drifting up. Liquid chlorine also causes the pH to rise when added to the pool water.

What can I do to raise the pH in my Pool?

HOW TO RAISE pH IN POOL. To raise pH in pool use washing soda, dosa ash or Borax. Aerating the water will also raise pH in pool water. If the pool has a fountain or water feature, it can be run to raise the pool water pH. Use chemical reagents or test strips to find the current pH.
