We all have basic knowledge to our chemistry subjects. One of the widely tackled subjects is getting to know what acid and base is. These solutions have wide contributions in making certain products in our world today. These products are things that we use in our daily lives: from maintaining hygiene even until the food that we serve on the table. Just a review on what it is all about; acids are solutions that are made of chemicals dissolved in water that can turn a litmus paper to red. Its ph level is below 7.0. On the other hand, base solutions turn litmus paper to blue and have a ph level above 7.0.

This concept is also important in the aspect of pool maintenance. Your swimming pool water is not only pure water but chemicals are added in it. It might be scary to realize that you are actually swimming in a bowl mixed with it. However, they are necessary to keep the water safe not only to the swimmers but also to the materials used in your swimming pools. You have to realize that maintenance of acid base balance in pools is important because you do not want an expensive pool pebble go to waste easily that can also result to costly repairs.

The concept of acid base balance for swimming pools is maintained through determination of total alkalinity. Water in your pools can change their ph easily especially when it used more than often. For you awareness, the normal ph for your waters falls in between 7.2-7.6 while for some upper limit may reach 7.8. On the other hand, total alkalinity should fall between 80-125 parts per million.

Now what is the effect of high alkalinity and too low ph? A very low ph means it is acidic; therefore, your water can become aggressive and can easily corrode metals components of your pool. It is not only limited to the bars used to make your pools but it can also affect the ladders that you have installed and other additional features for your pools involving metals. On the other hand, too much alkalinity is even more dangerous to manage because it is difficult to change. This is what they call the ph lock. No matter what you do, the current ph level will stay as is. Thus, problems like scaling can be inevitable.

You can use certain chemicals to correct the acid base balance in your pool pebble waters. Some of them are:

? Sodium bicarbonate- used to raise the alkalinity.
? Muriatic Acid- Used to lower the ph
? Sodium Bisulfate- This is an alternative to muriatic acid.

Note: The amount used for this chemicals are based per certain gallon of water.

You can always do something to your imbalanced pool waters before it can cause harmful effects to its structures and to the swimmer. Nevertheless, as pool owner you should do your best in religiously checking the ph. The simplest way to do it is to use litmus paper and have it dipped on the water.

Calcium is one of the minerals that are very important for human growth and development. Bone development is directly attributed to it. Most of us drink calcium supplements like milk and other milk products in order to meet the required level of calcium level in the body. However, as humans we also need to be careful in having too much of it because it can lead a myriad of signs and symptoms that can easily progress into a medical emergency. You also have to know having less of it will also have the same effect. That is why it is best to keep it with in its normal range and that is a blood serum level of 9-10.5 mg/dl.

Calcium is not only present in human body. Actually, it is also important for maintaining the chemistry levels of swimming pools. Just like our blood, water maintains a specific level of this mineral as a contributing factor to its hardness. As experts say, it contributes 97% of water hardness and the rest are just minute amounts. They are measured in terms of calcium hardness. The level to be maintained is around 200-400 parts per million. While other resources say it should be around 150 to 330 parts per million. Some people have set their own acceptable level, which is more manageable for them in handling their pool pebble water.

Now what happens if the level goes too high and too low? It is similar to the concept of alkalinity. There are corresponding undesirable effects to the swimming pool if they not kept within the required level. Too low calcium hardness results to deterioration of your pool interior materials (most especially the plaster) and water can become aggressive. They can also result to erosion of grouts and oxidation of metals. These effects are even potentiated when the ph of the pool water decreases as well. On the other hand, too much calcium hardness results to scaling, calcification, cloudy waters and irritations. Scaling occurs when calcium carbonate are drawn. When this happens, they solidify causing sandpaper like texture in its early stages. Then it can slowly progress in to hard edges that can be harmful to you. Calcification is the term for the buildup of calcium causing them to harden.

You see it is best to keep in mind that calcium levels should be monitored because it is difficult to manage them. If they are too high in your pool pebble, you will have to undergo a tedious process of draining some of your pool water and adding fresh ones. If you were to raise the levels of calcium at a normal range, a type of chlorine with calcium content can be applied to the water. The most commonly used solution is calcium hypochlorite

Therefore, it is important for you to maintain the normal levels of calcium in your pool. You can have you water analyzed for its chemistry three to four times in a month just to be sure. Any abnormalities should have prompt actions.
