As long as it still has its “newness”, your pool might feel like one of the best in Durham Region or even in the whole of Ontario, but without providing for its maintenance needs, it will soon be as murky and dark as a mangrove swamp. When it comes to caring for Oshawa pools though, you need to learn a little bit of science—chemistry, to be exact. For one, you’ll need it to know whether you’re getting your pool’s pH levels right for optimum safety.

Ph and Pool

What is pH?
First described by a Danish biochemist, pH literally means “power of Hydrogen”. Essentially, it is a negative log of the concentration of hydrogen ions within a water-based solution. Basically, it measures the acidity or alkalinity of water or any solution for that matter, based on a scale with figures ranging from 1-14, 1 being the most acidic and 14 as the highest base concentration (7 is the neutral range).

Pool Water Application
Pool water should be kept as close to neutral as possible to keep it from damaging the pool materials and accessories (high pH concentration could lead to clogged filters and calcium buildup), as well as hurt your eyes (the pH of your eyes is neutral). Moreover, pH levels around 7.0-7.6 also allows the disinfecting property of chlorine to perform at its most optimal.

Lowering High pH
Since high pH means that your pool water is too basic, you will need acids to lower the pH back to the neutral range. Here are some tips from an article posted at Swimmingpool.com:

"The most common chemicals used to reduce high pool water pH are:

  • muriatic acid — typically 30% - 35% liquid hydrochloric acid
  • sodium bisulfate — granule or powder pH reducer, dry acid

Other acids that have been used in pool water are:

  • sulfuric acid — raises TDS levels and adds sulfates to the pool water
  • nitric acid — highly corrosive but is known to work well"

Raising Low pH
Inversely, base is needed to neutralize acidic pool water. Acid rain is one of the most common causes of acid accumulation, or just an overall low level of alkalinity. Corrosion of substances and surfaces that come into contact with them is the main problem that plagues such pools, so be sure to use chemicals with sodium carbonate, a relatively strong base also known as washing soda or soda ash.

If you think that you need further help in maintaining the pH balance of your pool water, don’t fret. You can rely on professionals from nearby Oshawa or Ajax swimming pool companies like Claudette’s Pools & Hot Tubs for pool maintenance services.
