A large swimming pool in the garden looks idyllic. However, not much work is required to make it work. Fortunately, quite a few products have appeared on the market in recent years to help win the constant battle against adversity.
Whether you have an indoor pool or not, whether you clean it every day or only twice a week, that is not the end of pool care. Only with the right water treatment can you achieve a truly clear water surface.
What is pH
]
The so-called pH or hydrogen index is a number that indicates whether a substance is alkaline or rather acidic. For example, the pH of human skin is between 4 and 6. As for pool water, it is between 7 and 8, ideally between 7.2 and 7.6.
The values should not be taken lightly
.
The decimal point also plays an important role here. If the pH of the water is below 7.2, it will destroy both the pool and your health. After a while, corrosion can rapidly develop (even in stainless steel materials) and the plastic sheeting that protects the pool can fade. It is also an unpleasant substance that reacts with chlorine and nitrogen, irritating the eyes.
As the scale value increases, the water tends to become more alkaline. In practice, this means that the disinfection (chlorine) becomes weaker and the water becomes cloudy, making it impossible to remove it. The lime water precipitates, clogs filters, and also produces an unpleasant chlorine odor and irritates the skin.
What to measure and adjust
Water can be measured very easily with so-called pH paper. When inserted into the water, the piece of paper is colored and the value can easily be determined using the scale provided.
If the results are not favorable, measures should be taken. The best option is to purchase a liquid or granular pH depressant or pH elevator. This is treated in the same way as chlorine.
If you cannot maintain the proper pH of the water for an extended period of time, try a stabilizer. This will do half of the work for you.
