Daily residual, 2.0 to 3.0 free available chlorine level. Use chlorine tablets fed through a 4 lb. floating chlorinator to maintain a consistent 2.0 to 3.0 ppm free.

Step # 2 – Shock

Use chlorine shock every 7 to 14 days in the summer and every 30 days in the winter. More frequent shocking may be needed in periods of heavy use, extreme heat, or rainy seasons. You can also use it to raise low chlorine level quickly. Normal dosage is 1 lb per 10,000 gallons. Add in the evening for best results.

Step # 3 – Algae Preventative

Use algae preventers regularly to prevent algae growth year round. In order for preventative algaecide to be effective, it must be added in sufficient quantity before algae has formed and the level must be maintained. Initial dose must be 8 to 12 oz. per 10,000 gallons of pool water, followed by a maintenance dose of 4 to 8 oz. per 10,000 gallons every week. Additions should be made directly to the pool the day after shocking.
