The majority of pool owners are not informed of proper maintenance procedures, thus potentially causing danger to the users. The chemicals in the water needs to be delicately balanced to increase the lifespan of the pool equipment as well we ensure the safety of pool users.
Chlorine
Through contaminated water, a person can contract Recreational Water Illness that can make them fall sick. It is for this reason that the level of free chlorine should be measured on a daily basis. The addition of chlorine will help to kill bacteria, for instance, salmonella and E-coli to keep users safe. The free chlorine level should be kept 1-3 ppm for the safety of residential pools.
pH
The pH will indicate the water acidity. Low pH will be an indication that the water is more acidic, wearing your equipment our prematurely. When pH is high, it is referred to as basic, which increases the chance of scale-forming. There are kits available to test the pH of water on a regular basis; you should ensure that water pH is kept within 7.2 and 7.6 on the scale that ranges between 0 to 14. You need a pH closer to that of the skin to reduce irritations on your eye and skin.
Alkalinity
Comfortable swimming will be possible when the total alkalinity is well- balanced. The alkalinity reading should be consistent and should be approximately 80-120 ppm. This also contributes to a pool-friendly pH level.
Calcium
The calcium hardness should range within 150 to 250 ppm. When calcium is too much, water will become cloudy, and a scale formation will develop. Your pool water will become more acidic when calcium is too low.
Stabiliser
The deterioration effects of chlorine will be prevented by using cyranuric acid (CYA) which act as a pool stabiliser. When the level of cyranuric acid go down, you will have to purchase more chlorine, and there will be a risk of running out of chlorine especially during a hot and sunny day. The addition of pool stabiliser should be done after testing its level since excess can cause more problems. 40 ppm is the ideal recommended level.
TDS
The level of Total Dissolved solids (TDS) should be maintained well to keep the level of chlorine balanced to prevent metal corrosion, scaly deposits, and eye and skin irritation. The TDS level takes into account concentrated minerals, which comes from things that enter the pool. The level of TDS should read less than 200-250 ppm, or you should drain the pool and add fresh water. You can keep the TDS at manageable levels by regular backwashing.
