During summer vacation, many people bring their lovely family members to the beach out of town (or even other countries) to refresh their mind. However, not all people have enough time (and or the budget) to travels to a different country or just different city to swim or chill up at the beach. Sometimes, they just went to a water boom or water park to play in the freshwater pool while sliding at the fun water slides.
A freshwater pool at the amusement park generally designed in a shallow water (50-150 cm) but in a very wide area. To assure the safety of all visitors, the management at the water pool have their professional staff to maintain the water quality.
Water quality is not always about the hazardous material inside the water but the special knowledge on how to balance the pH in a pool also an important one.
The ideal pH water in a pool
Acidity level of water is known by water pH which scaled from 0 (acid) to 14 (base), while 7 is categorized as neutral water pH state. To make the water in a pool safe and comfortable for the swimmer, pH level of the water have to be maintained at 7.4 which is similar with the human eyes and other mucous membrane pH. Either lower or higher than 7.4 will be dangerous especially for human eyes (cause skin and eyes irritation).
In another perspective, low pH of water in a swimming pool is categorized as the aggressive water which may cause some damaged to the pool components. In another hand, high pH of the water will make the lime precipitations and a very low chlorine disinfection.
There are several things which may reduce or increase the pH of water like disinfectants, natural evaporation, debris or even the waste from the swimmer.
How to increase or lower pH of water in a pool
This is important of how to balance the pH in a pool. As explained, if the water pH level is below of 7.4, the maintenance staff will do several actions to increase the pH of the water in the safe state. This work seems to be a simple work but not an easy one. To increase the water pH, people use the pH increaser material. To reduce the water pH, people use the pH reducer.
pH increaser material is commonly known as the soda ash, which is known as the safe and effective material made from sodium carbonate (a quick dissolving chemical feature). For the example, if the water pH is 7.2, it is recommended to put 1 lb of sodium carbonate to 10,000 gallons of water.
To keep the water still in a safe state, always keep in mind not to put more than 4 lb of sodium carbonate per 10,000 gallons per application.
On the other corner, pH reducer has two well-known material named dry acid and muriatic acid. Dry acid made from sodium bisulfate in a granule shape. To apply the dry acid correctly, always dissolve it in a bucket of water and then put it to the pool instead of directly to the pool. To protect the staff who works with the dry acid, always wear the safety google and proper cloth.
Another popular pH reducer id the muriatic acid which is made from hydrochloric acid. Ideal dosage to reduce pH 7.8 at 15,000 gallons of water, you can put 0.25 gallon of muriatic acid and let the circulation system works. To make sure that the pool is in a safety state post of the dry acid or muriatic acid application, please wait at least 4 hours before allowing people to use the pool.
The important thing of how to balance the pH in a pool is improving the safeness. To improve the safeness since you use the chemical substance on reducing or increasing the water pH, always read carefully by every instruction provided by the chemical substance packaging and follow the exact instruction. If you are in doubt, better to hire the professional pool water treatment technician to do the job than you get it done by yourself.
Other water trouble at the pool
Excluding the water pH itself, there is another water trouble in an appearance of green water at the pool. The green water is caused by two subjects, first is the low chlorine level or the water pH is too high, second, those conditions will initiate the growth of the algae. To solve this, simply put the chlorine (usually in a tablet shaped) into the pool.
Another cause (but rare) of green water at the pool is the copper level in water or caused by the tree pollen. To make sure what causes the green water, first check your filter to see if there is the remain of the pollen. To get rid of the tree pollen at the filter, simply clean it under the jet streamed water. If there is no tree pollen, buy test water pack at the store to check the copper level at your pool completed with the remedy.
Basic pool maintenance to keep the water clean and clear
After knowing about how to balance the pH in a pool you have to know the basic (routine) maintenance which needs to be done regularly to keep the water at the pool stay clean and clear. First, you need a pump trap basket which will catch all floating debris and waste.
Second, you have to use the skimmer basket to pick up any leaves or debris. Always have the leaf net to manually catch the remaining leaves which may float at the pool.
Another routine maintenance activity is checking the circulation pump, including the filter. Sometimes there is a waste like hair from the swimmer or even small leaves trapped at the circulation pump filter. To make the circulation pump optimally works, make sure it’s filter is clean.
Always keep the pool water pH stay in balance along with the clean and clear water appearance, since it is not only good for the health and safety of the swimmer, but also for business (if it is a commercial pool). Reducing or increasing water pH is not allowed to be applied more than once, otherwise, you have to drain the whole water and refill it with the new water.
