Dirt, rust and other minerals can stain the finish of your plastered pool. If the stain is organic; from leaves for example, a small amount of granular chlorine added at that location and allowed to settle on the stain will usually remove it instantly. Other non-organic stains will not be removed by chlorine. Do not place chlorine tablets directly into the pool. They will stain and etch the pool plaster. If chlorine doesn't work, acid usually will. Draining and acid washing will remove a thin layer of plaster (and stains), exposing fresh, new looking plaster beneath. Stains can also be sanded with pumice stones or wet/dry sandpaper.
How long do I have to wait to use my swimming pool after chemical treatment?
Generally it is safe to use your pool after chemicals have dispersed throughout the pool, usually 15 minutes to one hour. If shocking your pool, wait until the chlorine levels drops to recommended levels
How often do I need to test my pool water?
Weekly testing works for most backyard pools, but the best bet is to test your pH and chlorine levels at least twice per week. Chlorine should be fed continuously through a chemical feeding device to maintain a consistent level.
What does it mean if I smell a strong chlorine odor in my pool or hot tub or it burns my eyes?
A common misconception, even among some pool and hot tub "technicians," is that the strong odor of chlorine means there is too much chlorine in the water. This is absolutely incorrect and in fact, the opposite is true. There is not enough chlorine to neutralize the ammonia in the water. More chlorine-based product should be added to solve this issue.
What is the Correct Balance for My Pool Water?
In order to prevent scaling or corrosive action and to achieve maximum swimmer comfort, pool water should be balanced to the following levels:
200-250 ppm (Gunite)
175-225 ppm (Vinyl)
What causes Chlorine odor, red eyes and itchy skin?
These unpleasant conditions indicate that the pool water has not been properly treated. A common cause is high levels of chloramines, formed when chlorine combines with body oils, perspiration, urine and other contaminants brought into pools by swimmers. Contrary to what most people think, a strong chemical smell is not an indication of too much chlorine in the pool. In fact, the pool may actually need additional chlorine treatment to get rid of chloramines and sanitize the water.
What is the difference between the chemicals that a professional pool supply store sells compared to a big box retailer?
A big box retailer will not stock the variety of chemicals that a professional pool supply store can provide. You may be able to choose from several different brands at a professional pool supply store. Also, most of the highest quality brands can only be found through authorized dealers and NOT in a mass merchant.
When do I need to shock my pool?
Routine shock treatment is necessary to destroy water contaminates that reduce the efficiency of the disinfectant or sanitizer. Contaminates like hair spray, suntan oil, cosmetics and other organic materials react with chlorine and cause eye or skin irritations and an unpleasant chlorine odor. Most often pools are inaccurately accused of having too much chlorine when this problem is present.
Why should I purchase pool chemicals from a professional pool store instead of a big box retailer?
The main reason that you should purchase chemicals from a professional pool store instead of a big box retailer is the knowledge and expertise of the pool professionals. Your swimming pool is a huge investment. You want to be sure that you are purchasing the right chemicals and treatment to prevent problems in the future. In addition, professional pool retailers offer reputable brands that are proven in the industry to function consistently and efficiently. You can damage your liner or gunite pool or hot tub by using poor quality chemicals, which can cost you much more money in the long run. Not to mention the ill effects some of these can have on your skin, hair, and eyes!
Why is it important to be sure that my pool water's chemistry is correct?
You want to be sure to provide a sanitary swimming environment, balance the water to protect the equipment and pool surfaces and provide inviting, sparkling water to swim in.
When should I clean my filters?
Check the pressure on your filter tank periodically. This will ensure that you will have proper flow and chlorination in the system. When the filter gets dirty it will not operate properly. If you have a cartridge filter they will need to be taken out and cleaned. If you have a sand and D.E. filter those can be backwashed. The general rule is that you need to know what the normal clean pressure is with your system in pool mode (make note the position of any water accessories such as tanning ledge bubblers and ensure they are in the same position when reading pressure each time, otherwise the reading is not accurate). Once it reaches 10 PSI over your initial clean pressure reading, it is time to clean or backwash your filter. For example: If your clean pressure in pool mode with bubblers open halfway is 12PSI, then you would clean filter at 21-22PSI.
