Algae
Microscopic plant-like organisms. They find their way into the pool by rain or wind and grow in colonies, resulting in algae blooms. The most common pool types are black algae, blue-green algae, green algae and mustard algae. Maintaining proper sanitizer levels, shock treatments and super chlorination will help to prevent or destroy algae.
Algaecides
Products that prevent or control algae growth. Algaecides are often formulated for a specific type of algae in varying strengths.
Alkalinity
A measure of the water's resistance to change in pH. It is composed of the hydroxides, carbonates and bicarbonates in the water. Can be measured by use of a test kit or test strips made for that purpose.
Ammonia
A nitrogen-containing compound introduced into the water by swimmers as waste (perspiration or urine) or by other means. It quickly combines with chlorine to form bad-smelling chloramines, which are harmful to our health.
Anchor wedges
Metal anchors fasten ladders and other permanent pool accessories into concrete. Concrete wedge anchors work by inserting them into a hole drilled into concrete. The concrete wedge anchor is then expanded, wedging itself securely in the concrete. These anchor wedges may be unfastened and the pool accessory removed for the winter.
Antifreeze for Swimming Pools (Non-toxic)
This antifreeze is placed in the plumbing lines of in-ground pools to prevent freezing. Non-toxic antifreeze is specifically formulated for swimming pools so that in the spring it is safe in your pool water. DO NOT use any other antifreeze in your pool lines.
Backwash
The process of thoroughly cleaning a pool filter pump by reversing the flow of water through it with the dirt and rinse water going to waste.
Bacteria
Microscopic organisms, some of which are harmful to bathers.
Balanced Water
The proper ratio of mineral content and pH that prevents pool water from being corrosive or scale-forming. Ratio can be determined by routinely using pool water test kits for these specific purposes.
Bromine
A halogen element used as an alternative sanitizer for pools.
