How to Flock a Pool

A cloudy pool is caused by algae and minute particles of suspended debris that circulate freely through the pool filter. Restore the clear sparkling mountain-stream appearance of your pool by settling these particles with one of the patented flocking chemicals available from your local pool outlet---but do not flock you pool during chemical shock treatment. Stabilise the pool pH first and remove loose surface and underwater debris with a skimming net and pool vacuum before using flock removal chemicals.

Loosen clinging algae by brushing the side and bottom of your pool with a long handled pool brush.

Apply the pool flocking chemical by following the directions printed on the plastic bottle; this is usually at a rate of 236ml per 10,000 gallons of water. Pour the chemical slowly into the skimmer while the pump is running in the circulating mode.

Leave the pump on for two hours to allow the chemical to mix thoroughly with the pool water.

Turn the pump off and allow enough time for the debris to settle; this could take anywhere from 12 to 48 hours, but usually works overnight.

Switch the pump to the "waste" setting and vacuum the pool thoroughly with a pool vacuum attachment after the debris has settled.

Continue vacuuming, with the pump set to the waste setting, daily for the next five to seven days to allow the chemical action to settle any remaining water-born particles.

Top up the pool with a garden hose once the water is crystal clear.

Tip

For pools without the circulating facility, dilute the required amount of flocking chemical into a bucket of water; stir thoroughly before walking around the pool and slowly pouring the mixture in. Double or triple the recommended dose of chemical to speed up the settling process if desired. Remember to reset the pump to the recirculating setting after each vacuuming session.
