SpaGuard Chlorinated Concentrate can be used as both a sanitiser and an oxidiser. It is completely soluble, so it does not cloud the water.
With the pump running, add 15 grams of Chlorinated Concentrate per 1,000 litres every 15 - 20 minutes until 2.0 - 4.0 ppm free chlorine residual can be maintained.
Use Chlorinated Concentrate as needed to maintain 2.0 - 4.0 ppm free chlorine residual. Chlorinated Concentrate may be needed nightly in a heavily used spa or as infrequently as once-a-week in a moderately used spa.
Add 50 grams per 1,000 litres directly to the spa with the pump running. Do not enter the spa until chlorine level drops to 5.0 ppm or lower.
