In regards to a swimming pool
Answer
High chlorine demand is the inability to keep adequate chlorine in pool water, even though the water is balanced and properly maintained. Various contaminants increase oxidation levels, consuming chlorine faster than it can be replaced by automatic feeders or normal shocking. Symptoms can include slimy or slick pool walls and cloudy water, although water can be clear and still have a high chlorine demand. A sudden drop in cyanuric acid can be an indicator that there is a chlorine demand problem, as the CYA reading is often masked by the demand. If this occurs, do not add stabilizer. Another form of chlorine demand is a high level of combined chlorine that cannot be broken by successive shock applications. Often this is caused by the presence of ammonia in the water. This can come from fertilizers, pesticides, and even fill water.
1.Free available chlorine (or RESIDUAL CHLORINE) - is the amount of chlorine in the pool that can sanitise or disinfect the water and is the important measurement for us.
2.Combined chlorine - consists of undesirable, bad-smelling, irritating compounds which form when there isn't enough free available chlorine.
3.Total chlorine - is the total amount of chlorine in the water. It includes both free available and combined chlorine.
We are interested in how much available chlorine there is in the water - chlorine that can act on foreign substances in the water to keep the pool clean and safe for the swimmers.
Too little chlorine results in algal and bacterial growth, waterborne illnesses, cloudy water and insufficient sanitation of the water.
Too much chlorine can result in eye, nose and skin irritations. Remember, too, that the chlorine in the pool is carcinogenic and we should aim to keep its level to the minimum required for complete disinfection.
Test kits which use tablets rather than liquid reagents are preferred. The tablets are easier to use and provide more accurate results. Also make sure that the chlorine measuring tablets are "DPD" as only these can measure the free available chlorine.

Cleaning your pool is a must to ensure bather comfort and protect your equipment. How to clean your pool is simple, and we've asked pool professional John Kistler to fill us in on the whys of pool cleaning.
Instructions
Difficulty: Moderately Easy
Steps:
Step 1 Use a manual brush and pool vacuum on all areas of the walls and floor at least once a week, even if your pool is equipped with an automatic system, says John Kistler of Sunflower Pool & Spa in Salina, Kansas. There are some places in every pool that the automatic cleaning systems miss.
Step 2 Pay particular attention to corners, stairs and other hard-to-reach areas that get little circulation.
Step 3 Keep your pool maintained. A clean pool is also a function of a working filtration system and proper pH levels. Use a sanitizer to help fight bacteria, and shock the pool on a regular basis (see How to Shock a Pool) to help keep it clean and crystal-clear.
