As a swimming pool owner, you should understand the importance of the pH level of your pool water. If your pool water has a high pH level, that means that the water is too alkaline. High pH levels can be problematic for many reasons, so it's important to monitor the pH of your pool and adjust it right away if it's too high. Here is some basic information about why the pH level matters and a few reasons why yours may be high.
Why Does a High pH Level Matter?
Pool water that's too alkaline can end up cloudy and may even cause stinging in your eyes. The alkaline nature of the water can also dry your skin out, causing it to itch and feel uncomfortable. The biggest issue, though, is the fact that the high alkaline nature of the water may actually inhibit the chlorine, leaving your water vulnerable to bacteria.
What Are Some Common Reasons for a High pH Level?
There are a variety of reasons for a high pH level in your swimming pool. In order to treat the problem effectively and prevent it from happening again, you'll need to understand what's likely to be the culprit.
General Water Alkalinity – When the total alkalinity of the water (which includes carbonates and bicarbonates) is high, you're going to find that your pool water has a high pH level. You'll have to treat the water with an acid product like sodium bisulphate or muriatic acid to adjust it, and you may even need to treat it frequently if this is a perpetual problem with your water source.
Chemical Pool Treatments – If you are treating a low pH problem in your swimming pool with a sodium bicarbonate product, you can inadvertently create a high alkalinity problem in your pool. Treating pH levels requires a precise calculation based on the amount of water in the pool and the current pH, so if you miscalculate and over-treat a low pH, you could inadvertently cause the water to become too alkaline.
Pool Shock – If you're getting your pool ready for the season or have to treat the water with a chlorine shock treatment for any other reason, it could interfere with the pH level. Most shock treatments are made from either calcium or lithium hypochlorite, both of which have pH levels over 10. If you shock your swimming pool, follow up right after with pH testing and adjustments.
If you find yourself struggling with your pool water testing and treatment, you should talk with a local pool cleaning and maintenance company like KC Pool Services.
