Description
This is a case of twelve 1 pound bags of chlorine that is used for effective super chlorination. This calcium hypochlorite product is a dry granular that is fast dissolving. Calcium hypochlorite destroys organic waste, controls algae and kills bacteria.Active Ingredient of this Omega Shock: 68% Calcium Hypochlorite and 32% Other Ingredients.
Directions for Adding Omega Shock to your Pool:
Shock should be used at start-up, once a week or as necessary to maintain your pool chemistry. First, check and adjust pH between 7.2 and 7.6. Add this product when no bathers are present. Scatter 1 or 2 ounces of shock per 1,000 gallons of water to yield an available chlorine residual of 5 to 10 ppm. Do not enter pool until the chlorine residual has dropped to a level of 2 ppm as determined by a suitable test kit.

Metal CorrosionCloudy Water
| Cloudy Water Causes | Solution | Preventive Measures |
| High pH | Bring your pH into the desired range of 7.4 - 7.6 ppm. | Maintain a proper pH level by using Haviland pH Reducer. |
| Dirty Filter | Check filtration system. Backwash if necessary. | Use Haviland Liquid Filter Cleaner each spring and fall. |
| Low Free Chlorine Residual | Bring free chlorine into desired range of 1 - 3 ppm. Shock if necessary. | Maintain a proper level using one of the Haviland chlorinating products. |
| High Total Alkalinity | Test total alkalinity and adjust accordingly | Lower total alkalinity to their ideal levels using Haviland pH Reducer. |
Green Water
| Green Water Causes | Solution | Preventive Measures |
| Green Algae (hazy water) | Shock the pool using chlorine based shock at 1 lb. per 10,000 gallons. Let circulate overnight and then adjust free chlorine residual to 1 - 3 ppm. | Add Haviland Algae Kil 50 or Haviland Combat 60 every other week at a rate of 6 oz. per 10,000 gallons |
| Copper in Fill water (clear water) | Use Haviland Rust-N-Scale at a rate of 6 oz. per 10,000 gallons. Let circulate overnight before adjusting chlorine or pH. | Add Haviland Rust-N-Scale every other week at a rate of 6 oz. per 10,000 gallons to prevent stains due to copper in the water. |
Reddish Brown Water
| Red/Brown Water Causes | Solution | Preventive Measures | Dissolved Iron or maganese in water | Adjust pH to 7.4 - 7.6 range. Use Haviland Rust-NScale. Let pump run continuously until clear. | Add Haviland Rust-N-Scale every other week at a rate of 6 oz. per 10,000 gallons. |
Eye & Skin Irritation
| Eye Irritation Causes | Solution | Preventive Measures |
| Combined Chlorine (chloramines) level too high | Shock the pool using one of the Haviland shock treatments. Let circulate overnight and then adjust free chlorine residual to 1 - 3 ppm. | Shock treat every other week, after heavy use or rain. Test for free chlorine residual daily |
| pH level too high or too low | Adjust pH by using Haviland pH Increaser or Haviland pH Reducer to bring pH level to ideal range of 7.4 - 7.6 ppm. | Test pH level daily and maintain pH in 7.4 - 7.6 range. |
Chlorine Odor
| Chlorine Odor Causes | Solution | Preventive Measures |
| Combined Chlorine (chloramine) level too high. The cause is NOT too much chlorine but not enough free available chlorine | Shock the pool using chlorine based shock at 1 lb. per 10,000 gallons. Let circulate overnight and then adjust free chlorine residual to 1 - 3 ppm. | Test pH level daily and maintain pH in 7.4 - 7.6 range. |
Calcium Scale Formation
| Calcium Scale Causes | Solution | Preventive Measures |
| pH too high/Total Alkalinity too high | Add Haviland pH Reducer to bring pH into 7.4 - 7.6 ppm range and to bring total alkalinity down to 100 - 175 ppm. | Maintain pH level in 7.4 - 7.6 range. Maintain total alkalinity level in 100 - 175 ppm |
| Calcium Hardness level too high | If hardness level is too high, some water may have to be drained. Add Haviland Rust-N-Scale per label directions. | Add Haviland Rust-N-Scale every other week at a rate of 6 oz. per 10,000 gallons. |
Corrosion of Metal Parts
| Corrosion Causes | Solution | Preventive Measures |
| pH too low/Total Alkalinity too low | Add Haviland pH Increaser to bring pH into 7.4 - 7.6 ppm range. | Maintain pH level in 7.4 - 7.6 range. Maintain total alkalinity level in 100 - 175 ppm. |
| Calcium Hardness level too low | Add Haviland Water Hardness Increaser to raise the calcium to 180 -275 ppm. | Maintain calcium level at 180 -275 ppm. |
