Alkalis are best known for being bases (compounds with pH greater than 7) that dissolve in water. Alkaline is commonly used as a synonym for base, especially for soluble bases.Saturday, December 06, 2008 8:02 PM
Alkaline refers to the condition where the water's pH is above 7.0 (neutral) on the pH scale. It is the opposite of acidic. Alkalinity is the amount of carbonates and bicarbonates in the water, measured in "parts per million" (ppm) of Total Alkalinity.Saturday, December 06, 2008 8:02 PM
- Alternative SanitizersOzone gas is basically an active form of oxygen that reacts with bacteria, viruses, algae, and other impurities in the water. At its low concentration levels in the water it has no effect on your skin and eyes. Many municipal water purification plants use ozone to treat drinking water. When the ozone gas dissolved in water comes in contact with impurities it oxidizes them as chlorine chemicals do. It also causes particles, body oils, and suntan oils, etc. to clump so the filter can remove them more effectively. Most ozone purifiers for pools and spas use only about 0.5 amperes when they are running. This is about the same amount of electricity a 60 watt light bulb uses. Since the ozone generator unit only runs when the filter pump is operating the total amount of electricity used is not great.

- ALUMINUM SULFATE
Also known as "alum;" this product is used as a flocculent which attracts suspended particles in the water together (green or cloudy pools). "Alum" sinks everything to the bottom which is then vacuumed to waste. A small amount of "alum" can also be used as a sand filter additive.

A negatively charged ion, which has more electrons in its electron shells than it has protons in its nuclei, is known as an anion due to its attraction to anodes.

- AquaCheck Test Strips
Test strips are at minimum comparable in accuracy to liquid color comparator tests. Because AquaChek test strips are more convenient, we believe they actually deliver greater accuracy. They reduce the chances of human error associated with liquid kits, which require measuring samples and counting drops of reagent.

- Automatic Cleaners - Pressure Side Cleaners / In-Ground
These cleaners are those that attach to the pressure side (return) of your circulation system. The water that is being pumped or "pushed" back to the pool powers these units which have their own hydraulic power plant inside. Being on the pressure side, these units have distinct advantages. They are helpful in distributing clean, filtered water around the pool and having their own debris bag means that they don't compromise the filter system. Even with the bag full, a pressure cleaner still operates, stirring debris up. It just won't suck up any more debris until the bag is emptied.

- Automatic Cleaners - Robot Cleaners / All Pool Types
The advantages to owning a robot cleaner include their self contained filter, which is easily cleaned. They also do quite well with their coverage. Some units are computer chip controlled, and some even have remote controls so you can steer the unit from a lounge chair! Being that they are the only cleaners not attached in any way to the pool's circulation system, they produce no resistance or back pressure on the filtering. Their cost can be more than suction or pressure side cleaners.
