You may wonder why it is so important to have the Ph and the Alkalinity balanced in your pool. Interestingly enough, we have Ph in our bodies. The optimal Ph for our bodies is 7.4 and the safety range in swimming water is between 7.2 and 7.8 ppm (parts per million). If the Ph in a pool is too high the chemicals in the pool begin to not function as they should. Dangerous bacteria can breed in the water and can be harmful if it makes it inside the human body. There is also a hazard to your pool as well as very high Ph can cause cloudiness and scaling on the walls of your pool.
On the flip-side, you don’t want the Ph in your pool to be very low either. Low Ph can cause skin irritation and can cause burning in your eyes. Low Ph also causes the other chemicals in the pool to not function optimally. Low Ph can also corrode anything metal in the pool (i.e. ladders) and wrinkle your liner.
So what does Alkalinity have to do with any of this? A high alkalinity leads to a higher Ph and a low alkalinity leads to a lower Ph. Alkalinity is a sort of twin to Ph and they go hand-in-hand. If the Ph and the alkalinity are low in your pool water, you don’t necessarily need to put in Alkalinity-Up and Ph-Up. You could probably just put in alkalinity and that will also raise your Ph levels. If you are unsure about how to test or how much to add. You can bring a water sample to a local pool store to have your water tested. The Pool Doctor conducts free water tests. Once we test your water, we will know what range your chemicals are in and will be able to tell you what you need to put in your pool also how much of the chemical needs to go in your pool. Amounts of chemicals will vary based on the volume of your pool, so knowing the volume of your pool or the dimensions (length, width, diameter, depth, etc.) will be able to give us an accurate reading.
