PH is the amount of acid or alkali in the pool water and everything can affect the levels from the weather to oils and even cosmetics. It is crucial to keep this in the recommended amount because having too low of pH can cause algae growth, and the water becomes corrosive, destroying the mechanical components of the pool and can make hair become brittle, skin irritation, and irritation to eyes. Low pH can affect many things and can hit you hard right in the wallet as well. It is not cheap to replace the pump, lining, or plaster. The lining or plaster will be eaten away by too low of a pH resulting in having to drain your pool and get it redone; it will cost thousands of dollars.
The recommended level of pH is between 7.2-7.8. Anything above 7.8 the water becomes vulnerable to becoming cloudy and forming a slimy scale on the pool liner and equipment and also causes skin irritations, sometimes even burns. Calcium, the main mineral in water cloudiness becomes very unstable and insoluble causing it to “fall out” and cause cloudiness. Not keeping pH level below 7.8 can cause big damages. If it stays high all the time you risk poor circulation because of scale build up thus creating pressure on the gaskets and hoses causing leaks and shortening the life of your pump, poo heater, chlorinator (if you have one) and much, much more!
PH can be caused by many factors, but the most common cause is from the sanitizer that is used. A high pH will also lessen the effects of chlorine making you having to put in more and more chlorine. They make chemicals to increase or decrease the level of pH that you need. There is pH Increase and pH down and that comes in two forms: liquid acid or dry acid. Always use caution using the pH balancing chemicals because any type of acid eats away at things, skin, clothing, and can cause blindness. Remember to always add acid to water, never add water to acid. Take a bucket and fill it 3/4 full of water and then add the acid and carefully poor the mixture to the around the deep end of the pool. Allow 4 hours to circulate and then retest the pH levels.
Improper pH levels can also effect how, when, and if algae grows. High pH levels can cause algae to grow because it lessens the effect of chlorine, which, is the go-to for preventative algae. Using an algaecide can help reduce the issues, but does not necessarily take the chance of it happening away for good. Proper pH balance can cut your costs of pool maintenance by half! Always keep up on the levels, because once something gets thrown off, they all get thrown off and it is not good for your pool, people, or the mechanics of the pool. Algae does not just happen, they need certain water conditions to occur.
