This is why a lot of people use Trichlor pucks in a floating dispenser so that chlorine is more continually introduced. Unfortunately, continued use of Trichlor builds up Cyanuric Acid (CYA). The Chlor-Brite you have been using is Dichlor when increases CYA even faster. The following are chemical facts independent of concentration of product or of pool size:
For every 10 ppm Free Chlorine (FC) added by Trichlor, it also increases Cyanuric Acid (CYA) by 6 ppm.
For every 10 ppm FC added by Dichlor, it also increases CYA by 9 ppm.
For every 10 ppm FC added by Cal-Hypo, it also increases Calcium Hardness (CH) by at least 7 ppm.
So even with a 2 ppm FC per day chlorine usage, Trichlor would increase CYA by over 35 ppm PER MONTH if there were no water dilution. Higher CYA levels make chlorine less effective -- basically, it is the FC/CYA ratio that determines the active chlorine level that kills pathogens and prevents algae growth.
You should read the Pool School to learn how to properly manage your pool. Your cloudy water is likely nascent algae growth before it turns into a full-fledged bloom. You need to shock with chlorinating liquid or bleach (or possibly Cal-Hypo if your CH is low).
Perfect advise! It worked and thank you for the information!
