- MSDS/SDS (pdf)
DescriptionThis 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.
- 68 % Calcium Hypochlorite
- Strong oxidizing agent
- Can be used with chlorine and salt water pools

Troubleshoot Your Water
- Cloudy Water
- Green Water
- Brown Water
- Eye Irritation
- Chlorine Odor
- Calcium Scale
- Metal Corrosion
|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 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 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.|
