Doug Allen Pools offers a range of swimming pool chemicals to help balance your pool the easy way
The most common chemical used in the treatment of swimming pool water is chlorine. It not only eliminates bacteria and algae by disinfecting (killing) action, it also oxidizes (chemically destroys) other materials such as dirt and chloramines. Free Chlorine Level (FCL) is levels of active Chorine, Total Chlorine Level (TCL) measures combined level of active and inactive Chlorine. High inactive Chlorine can cause swimmers eyes to burn and may itch the skin, to remove Inactive Chlorine the pool must be Super chlorinated to activate the chorine.
The standard for Chlorine is 0.6 – 3.0ppm
To increase chlorine, chorine must be added (there are many types of chlorine some raise pH levels others may decrease this level)
A salt chlorine generator (also known as a salt system or a salt chlorinator) is a swimming pool chlorination system that creates chlorine from sodium chloride (salt). Before a salt chlorine generator can operate, the swimming pool water must have a salt concentration of 3,000 ppm (parts per million).
The standard for salt is 4.0-8.0
To increase salt, salt must be added
The pH level is critical to protect bathers and pool parts and surfaces. Low or High pH levels can irritate eyes and skin; it also indicates the water is corrosive or scale forming. Low pH tends to deposit scale onto surfaces. A high pH reduces the effectiveness of chlorine.
The standard for pH is 7.2‐8.0 (Recommended range 7.4‐7.6).
To lower the pH, (hydrochloric) acid must be added
To raise the pH, soda ash (sodium carbonate) must be added.
Total alkalinity, indicates the ability of water to resist changes in pH. Since pH is so critical to keep in the ideal range maintaining Alkalinity above 80ppm is important if Alkalinity gets to high (above 150ppm) the water often has a high pH that is difficult to reduce to 7.8 or less.
The recommended level for swimming pool water is 80‐120 ppm
To increase alkalinity Sodium Bi Carbonate is added
Cyanuric Acid (also called) stabilizer is used to protect Chlorine from sunlight. Some types of chlorine (dichlor and tricolor) includes Cyanuric Acid and therefore it can build up over time. Too much Cyanuric Acid may slow the sanitizing power of chlorine
The recommended level for swimming pool water is 50‐60 ppm
To raise the Cyanuric Acid, Cyanuric Acid powder must be added
To lower the Cyanuric Acid, a portion of the pool water must be removed and fresh water added.
When Hardness is to low water often is corrosive and extracts hardness from the pools surface (such as plaster). If Hardness is to high the water may deposit scale on the surfaces or clog pipes. By keeping pH, Alkalinity and Hardness in their ideal range water will not damage the pool or spa.
The recommended level for swimming pool water is 200-500ppm
To raise the Calcium Hardness, Calcium Hardness powder must be added
To lower the Calcium Hardness, a portion of the pool water must be removed and fresh water added.
Metals (Iron and Copper)
Metals in water can cause staining on the pool surface, it’s important to ensure metals are low as chlorine can mix with the metals and the water and surfaces can be colored or stained rapidly.
The recommended level for swimming pool water is <.03 ppm
To lower metals, Metal Remover will remove the metals to the filter and ultimately out of the pool.
There's nothing pretty about algae in your pool. For those who skipped science class, algae are plant-like single cell micro-organisms that are present in the air and spread by wind and rain.
In swimming pools, algae can form when protective products or Chlorine levels are low.
Black Spot Algae
Brush the affected areas vigorously to remove the protective coating from the algae. Add Pool Blackspot Remover or All In One Pool Algaecide directly on top of the affected area and leave overnight.
Brush the affected areas vigorously to remove the protective coating of the algae. Add All In One Pool Algaecide directly on top of the affected area and leave overnight.
Add All In One Pool Algaecide to the pool and leave overnight.
Phosphates are usually brought up when you have either green or cloudy water. The truth is, you will ALWAYS have phosphates in pool water. They are introduced to your pool in several ways, including:
Vegetation (i.e. leaves and dirt in your pool), Tap water, Makeup, lotions, hair products, Pool chemicals, Lawn fertilizers (if added directly into the water)
They are impossible to avoid, and they are “algae food.” Algae can digest phosphates which will help it grow quickly.
Handling and Storage of Chemicals
Care should be taken in the handling and storage of all swimming pool chemicals. The materials should be stored separately from one another and should NEVER be mixed, in order to prevent harmful chemical reactions from occurring. (Pool chlorine and pool acid, if mixed, produce chlorine gas; if inhaled, it can be fatal.) Chemicals should never be added directly to the pool while it is open for use! Time should be allowed for the chemicals to circulate throughout the pool before allowing swimmers to enter. (This rule does not apply to chlorine introduced through an automatic chlorinator.)
High temperatures chlorine dissipates faster, algae grows better, and the formation of scale (calcium carbonate deposits) is more likely to occur.
