Pool pH level - Balance Your Pool Water For Optimum Results!
The pH level of a swimming pool. What is this really? It is actually the measure of how acidic or how basic the water is in your swimming pool. The pH balance for a swimming pool is very essential to its overall water chemistry. Therefore it is vitally important that you learn how to test and adjust it.
This pool balancing factor is one of the most important element in swimming pool water chemistry.
The truth of the matter is that it affects every other element in the pool chemical balancing of your pool or spa water.
The pH levels for swimming pools are measured on a scale that ranges from 0 to 14.
Where a reading of 0 indicates an extremely strong acid base (acidic water) and a reading of 14 means a very strong base (basic water). 7 which is at the middle of the scale, means that the water is very neutral. This in fact is the neutral point for water. The most desirable pH level for a swimming pool or spa is between 7.2 and 7.6.
This range will keep your pools/spas slightly alkaline and it is the most comfortable range for the eyes of your human swimmers. The truth of the matter is that these ranges will also provide optimum use of the free chlorine content in your pools; thus giving your swimming pool optimum sanitation. This will also help in maintaining your pool water chemistry, so that it does not become corrosive or scale forming.
What happens when your pH level is too low?
Whenever the pH of your swimming pool or spa drops too low, the water will become very acidic. When this happens, the water tends to corrode or etch anything that it comes in contact with. Generally water that is acidic will be under-saturated or very hungry. This means that it will seek out something to dissolve and combine with.
Problems caused by low pH levels include...
Problems caused by a pH level that is too high include...
There are many factors that can affect the level of your swimming pool's or spa's pH. Some of these influencing factors include...
Controlling the pH of your swimming pool!This process is extremely important for several reasons. Firstly it provides comfort to your bathers (zero eye burns or irritations). Secondly the efficiency of your pool sanitizer is kept constant. Thirdly, you will be providing protection to the mechanical parts in your recreational water facility. Therefore you need to understand the best ways to control and maintain it.
However, before you make any attempts to adjust your pH, you should firstly test and if necessary, adjust your total alkalinity levels. Your pH is easily controlled if you maintain a proper level of total alkalinity. Often times when your alkalinity levels are correct, your pH levels will be correct also.
pH adjustment in your swimming pool!
Now for you to avoid any of the problems that I have listed above, you must maintain your pH levels between 7.2 and 7.8. However the most desirable level for pools and spas is between 7.4 and 7.6. In the meantime, if your pH is too low, you should run an alkali demand test.
This test, once done correctly, will let you know how much soda ash (sodium bicarbonate) you will have to add.
Never add more than 2lbs of soda ash for every 10,000 gallons of water in a single treatment process.
Make sure that your swimming pool pump/s is running before adding any chemicals to your pool.
Once you have allowed your pool water to properly re-circulate, retest once again. This will let you know if you have to carry out any further treatment. Caustic Soda is another pool chemical that is used to raise the pH in pools and spas. This chemical is sometimes added to swimming pools by means of a chemical feeder pump that is controlled automatically.
If your pH remains low, you may have to raise your total alkalinity in order to stabilize them. The table below gives you a pretty good idea on how to go about raising your pH levels in your pool or spa.

pH adjustment using Muriatic Acid!
Now if your pH is too high, you will need to carry out an acid demand test to determine the amount of muriatic acid that has to added. Adding muriatic (Hydrochloric acid) to your swimming pool lowers its pH level. Something to remember! Muriatic acid not only lowers your ph levels, it also lowers your alkalinity levels as well.
So be sure to check you total alkalinity after all treatment. Now you can use an acid salt such as sodium bisulfate which will lower your pH as well. Best practice here - is to add the acid to the deep end of your pool carefully.
Be sure to avoid pouring it near the wall of your pool or near any of its fittings. Special precautionary measure here: When you are using or diluting acids, always, always, add the acid to the water. Never add the water to the acid. The table below, can be use as a guide on how to go about lowering the pH level in your swimming pool. You would use this table, after you have determined that the pH needs to be lowered. A pH level testing is required first.

Maintaining the pH level in a swimming pool or spa is never easy. There are factors that directly affect the pH of your swimming pool. They include...
On the other hand, there are factors that directly affect your pH by raising it. These include...
Remember when using any form of pool care chemicals, there should be no swimmers present in the water. Your swimming pool should also remain closed until, the pool chemicals are completely dissolved and dispersed. This include all pool chemicals that are used to raise or lower your pH level.
