If the pool has just been opened, the water should be circulated for at least 24 hours before being tested.I have never been to Gallagher Pools and Spas before, but I am bringing in a water sample. How should I prepare it?Water samples should be taken from 18" below the surface of the water. If the pool has just been opened, the water should be circulated for at least 24 hours before being tested. If you get a chlorine reading higher than the max on your test kit, wait until the chlorine level comes down before testing the other elements of your water chemistry. Find a clean container that has never held other liquids than water(do not use soda bottles, shampoo bottles, or food jars. Bring at least 16 ounces of water if possible. You can use a clean ziploc bag in a pinch. When you arrive at the store, ask for a Gallagher Pools and Spas sample bottle. Make sure your name and phone number is written on the front of your bottle either on the bottle or on a piece of masking tape. Some customers affix an address label with their name on it to the front with their phone number.Are there any chemicals I should not store together?Acid should not be stored near chlorine products. Liquid products should not be stored near powdered products, especially chlorine. Liquid chlorine containers are vented and should always be stored vertically. Containers of powdered or tablet chlorine should always be closed after use, and never left out in the rain. Chlorine must be in a well ventilated area way from any metal items.I just added a chemical to my pool, how long do I need to wait before people can swim?After shocking the pool, you should wait at least one hour before allowing people to swim. If you have just added acid to your pool (either muriatic acid or pH Lower), you should wait 4 hours before allowing people to swim.How often do I shock my pool?The pool should be shocked every week. Check the chlorine level with a home test kit to determine the actual level of chlorine in the pool.How much shock should I use to shock my pool?If the chlorine level is 0.5 - 3.0 a "normal" shock should be added to the pool at a rate of 1 pound per 10,000 gallons of pool water.If the chlorine level is below 0.5 a "double" shock should be added to the pool at a rate of 2 pounds per 10,000 gallons of pool water.I use chlorine tabs/sticks. How many should I use?You should use 1 Gallagher's Chlorine Tablet for every 5,000 gallons of pool water, or 1 Gallagher's Chlorine Stick for every 7,500 gallons of pool water. The number of Chlorine tablets/sticks should not be increased, but can be decreased should your chlorine exceed 5 ppm.What is the proper chlorine level for my pool?Most pools should hold a normal level of chlorine (called chlorine residual) of 1.5-3 parts per million (ppm). Pools using an alternative such as the Pool Frog or Nature 2 systems can maintain a chlorine residual of 0.5-1.0 ppm.Why should I keep my pH in balance? What happens if my pH is too high or low?Keeping your pH balanced is important to proper water chemistry. The pH of your water confers many qualities on the water which can either make it much easier to take care of, or a nightmare. High PH can cause cloudy or colored water, irritate your eyes, form scale, and cause your sanitizer to function poorly. Low pH is a leading cause of eye irritation. It can also corrode your metal equipment, shrink and weaken your liner, burn your skin, etch your plaster and encourage stains. Consider this. The pH of your mucus membranes, such as your nose, ears and eyes is 7.5 . If your pH is vastly different than that, it causes irritation. This is one of the primary reasons we try to encourage keeping your pH as close to 7.5 as possible!Browse Chemicals Ask a QuestionSpaWhy is Bromine typically used in a spa rather than Chlorine?Bromine is more stable as a disinfectant at high water temperatures.
