ABSOLUTE FILTER RATING Filter rating meaning that 99.9 percent of essentially all of the particles larger than a specified micron rating will be trapped on or within the filter. Saturday, December 06, 2008 07:34 PM
Liquid (muriatic acid) or dry granular (sodium bisulfate) substance used to lower the pool's pH (toward a more acidic condition) or to lower total alkalinity levels.

ACID DEMAND A titration test used to determine proper amounts of acid (or pH decreaser) to reach correct levels. For example, to lower pH from 8.0 to 7.6, your pool may "demand" 2qts. of acid. Saturday, December 06, 2008 07:34 PM
Acid Washing Also called a drain & clean, an acid wash becomes necessary if the pool has turned into the "black lagoon". This may occur if the winterizing processis not done properly, or if the pool has been stagnant for a period of time so that algae has taken over. If you notice scaly, man-phibian creatures splashing around out back, it's probably time to drain & clean. Monday, December 22, 2008 05:53 PM
AIR BLEEDER ASSEMBLY Located on the top of the filter and sometimes accompanied by a pressure gauge, the bleeder is opened to release air trapped in the filter. Saturday, December 06, 2008 07:35 PM
Over 20,000 species known to exist. Algae may form on your pool surfaces or it may bloom in suspension. We typically know algae to be green but it may also be yellow (mustard algae), black, blue-green, or any shade in between. It may form separate spots or seem to grow in sheets. Pink algae is not algae at all but a form of bacteria. Algae are living breathing organisms that need warmth, sunlight, and CO² to thrive.
