WHAT DOES THE pH READING MEAN IN A SWIMMING POOL

clock June 6, 2017 03:00 by author medallionpools |

PH is a term that is used to measure whether something is acidic (low pH) or basic (high pH). This reading is expressed in a scale in a range from 0-14. Swimming pool water should be maintained at a neutral pH of between 7.2-7.6. Maintaining the proper pH level helps maintain your pool equipment, allows the chemicals to be more effective and makes the water comfortable for swimming.

A low pH reading can cause skin and eye irritation, damage the liner, damage the surface of concrete pools, and corrode your pool’s equipment. A high pH reading could cause cloudy water, scale to form, and sanitizer to be less effective. Some of the common causes of pH changes are:

• Chemicals- Chlorine tablets or sticks lower pH. Granular chlorine raises pH.

• Adding fresh water to your pool will change the pH levels.

• Dust and rain will change the pH levels.

• Swimmers and swimmers waste will tend to lower the pH.

• Algae growth usually raises the pH level.

It is very important that you have a good test kit for testing pH and also take a sample of your pool water on a regular basis to your pool store so they can test the readings for you and tell you how to adjust the pH level.



What Is Calcium Hardness And How Does It Affect A Pool Or Spa?

GLB Calcium Hardness Up

Calcium Hardness is the measure of how much Calcium is dissolved in the pool water. You do not want your Calcium Hardness to be to high or to low, that is why we suggest that your Calcium Hardness needs to be between 150 and 250 ppm (Parts per million). The ideal range is not always ideal for everyone it could change on the type of pool you have, or the type of chemicals that you are using in your system please consult a pool professional. If your Calcium Hardness is too high or to low you may experience some problems with your pool. You may see some corrosion or some pitting of some areas.

When your Calcium Hardness is to low your water becomes corrosive. When your water is corrosive it can very easily stain the floor and the sides of your pool. Not to mention the damage it can do to the metal parts of your pool, corrode plumbing fittings, do damage to the pump and heater. This can cause pitting on your pool decking surfaces and on the pool concrete. It may also etch your pools plaster and destroy grout if these were used in the making and installing of your pool.

When your Calcium Hardness is too high you could very easily clog your pools filter and it may also clog your pools heater elements. This will also cause scale build up on all of the pools surfaces. The water will become cloudy and the higher the Calcium Hardness is then more irritation will be cause to the swimmers skin and eyes. So this is something you defiantly want to keep in between the correct range because having high or low Calcium Hardness can both affect your pool in the incorrect way.



Automatic Chlorinators

The automatic chlorinator is a very efficient way to chlorinate your pool with large or small Trichlor tablets or Bromine slow-dissolving tablets to make sanitizing your pool or spa easy and automatic. If you do not have this unit, your options are;

1. Put the tablets in a floater

2. Put the tablets in the skimmer basket

3. Put the tablets in the pump basket

Any one of these three options will present you with a problem. The use of a floater is the lack of the ability to get the proper amount of chlorine in your pool. Since you do not have water flowing into the floater to dissolve the tablets, your pool water is going to be usually low in chlorine with the result being green water and algae build up.

When you place the tablets into your skimmer basket, they dissolve very quickly and it becomes very difficult to maintain the proper amount of chlorine in the pool. It can also deteriorate your skimmer basket and the seals and o-rings on your pump and filter. If you turn the pump off, chlorine will flow back into your pool causing a white stain in front of your skimmer.

If you place the tablets into your pump basket, they are also dissolving very quickly here and chlorine levels could be too high. This also will cause your pump seal to start leaking and your o-rings to wear out quickly with possible pump damage.

The automatic chlorinator is installed after the filter in the water return line going to the pool. It should be the last thing the water goes through before returning to your pool. These units are completely enclosed systems – no escaping fumes. Simple, trouble-free designs with no special venting required. Top loading makes it easy to add chemicals. You remove the lid and place the tablets inside. There is a control knob with different settings that will let you control the amount of chlorine being released into your pool. Note that every pool is different and you will need to adjust the settings based on your particular pool. Automatic chlorinators save time, reduce manual handling of chemicals and take the work and worry out of keeping your pool sparkling clean and ready to use.



What Is Total Alkalinity And How Does It Affect A Pool Or Spa?

GLB Alkalinity Up

Total Alkalinity is the measure of all of the alkaline substances that can be found in your pool or spa. Your main focus when dealing with Total Alkalinity is to measure your calcium carbonate, keeping your calcium carbonate in a safe range will help with the up keep of your pool and much more. Your Total Alkalinity should be keep between 80ppm (parts per million) and 120 ppm. When your Total Alkalinity is in this range it will prevent rapid pH changes in your pool or spa as well. It really helps to stabilize the pH.

If your Total Alkalinity is low there are many things that this could do to your pool or spa. With it being low it can corrode metal parts that are in the pool or spa, for example your steps, hand rails, pumps, etc. It can also stain the pools walls and floors, and make the water green. On top of all that it will also cause your eyes to burn and can cause your pH to bounce seemingly at random.

If your Total Alkalinity is to high it really makes it difficult to adjust the pH levels in the pool or spa. With the Total Alkalinity being to high it can also make your water cloudy and cause the chlorine to lose its effectiveness as a disinfectant. This could also cause your filter and heating elements to get clogged up. So keep in mind that it is very important to keep your Total Alkalinity in the correct range and it will make it a lot easier for you to be able to keep up with the up keep of your pool or spa.



What is pH and how does it affect a pool or spa?

pH scale

pH is the measure of the acidity of the water. The lower the pH the more acidic it is and the higher the pH the more basic it is. Maintaining pH, or potential Hydrogen, is simple and easy when you understand just a few basics. pH ranges from 0-14 with 7 being neutral.

Your pool or spa’s pH should be between 7.2 and 7.6. Your eyes pH is between 7.3 and 7.4, so the closer you are to 7.4 the less burning sensation you will have in your eyes. If your pool or spa’s pH is below 7 then the water becomes more corrosive and will start to wear away your metal components. For example your pump, your heater, and it also removes the plasticizers from the vinyl liner & pits the concrete, etc.

If you pool or spa’s pH is to high then it will start to build up scale. Scale can begin to form on the warmest parts of the pool, so the heater is the first victim. Scale acts as an insulator on the heat exchanger. That can run up the cost of operating your pool because you have to use more natural gas or electricity. And finally the higher the pH is in your pool or spa the less effective your chlorine will be, and the less sanitized it will be.
