Chlorine Maintenance
O.P. Aquatics Chlorine
There are many forms of chlorine available today which are effective bactericides. Those most commonly used are Sodium Hypochlorite Liquid Bleach, Chlorinated Isocyanurites, Calcium Hypochlorite, and Bromine. The selection of a chlorination program requires the thorough consideration of several factors including pool size, swimmer load, safety, simplicity of treatment and cost.
Sodium Hypochlorite Liquid Bleach
Generally speaking, large pools of 50,000 gallons or more use Sodium Hypochlorite Liquid Bleach for their sanitation program. This product has long been recognized as a fast acting and very effective bactericide. The bulk delivery method has reduced the cost per gallon to a point that makes this product one of the most economical and safest means of chlorination, as well as eliminating the problem of storage and handling.
Chlorinated Isocyanurates (OPAquatics Pool Brite Granular & Tablets)
This product is recommended for pools having a capacity of under 100,000 gallons of pool water. Its primary advantage is that when stabilized with OPAquatics Pool Brite Stabilizer, it will withstand UV Light.
Chlorine Treatment
The amount of chlorine required depends on the amount of impurities present in the pool water. For this reason, it is difficult to state the amount of chlorine any given pool will use in the course of a day. There are many variables
Sodium Hypochlorite Liquid Bleach Half Life
| Degrees Fahrenheit | Number of Days |
|---|---|
| 77º | 220.00 |
| 87º | 110.00 |
| 97º | 55.00 |
| 107º | 27.50 |
| 117º | 13.75 |
| 127º | 6.87 |
| 137º | 3.43 |
| 147º | 1.72 |

Chart indicates number of days required for 10 - 15% liquid bleach to lose one half strength at various temperatures.
FOR EXAMPLE: 15% Sodium Hypochlorite (Liquid Bleach) stored in your filter room with a temperature of 87º, would take 110 days to lose half of its strength.
