AlgaeFree Serious Stain Remover

No Need to Drain Water

Directions for use:

First: For best results let the chlorine level fall to 0ppm and adjust pH to 7.0. Backwash or clean the pool or spa filter and turn it off. Remove all plastics including covers, hoses and cleaners. DO NOT SWIM or filter during treatment until water has rebalanced and sanitized.

Recent Stains and Vinyl liners: For pools, add 200g of SeriousStain Remover per 10,000 liters of pool water (1.2kg per 60,000) dissolved in 10 liters of water and pour around edges of the pool. In spas use 100g per 2000 liters. This treatment further lowers PH. Brush the walls and floors after 24 hours and if the stains faded restore pH to 7.2 with a similar quantity of Alkalinity UP.

Severe and Old Stains: Add at double the dose (2.4kg per 60,000). In addition Hydrochloric acid pre-dissolved in a bucket of water may be added to further lower pH as follows.

Vinyl Pools - 500 mL of hydrochloric acid per 10,000L

Fiberglass Pools - 1 liter of hydrochloric acid per 10,000L

Concrete pools - 2 liters of hydrochloric acid per 10,000L for plaster,pebble and colour quartz finish, for painted pools in good condition, use does for fiberglass. Most marks, stains or coloured streaks fade completely in 2-3 days. To complete the treatment for severe or old stains raise the pH back to 7.2 with 2kg dose of Alkalinity Up pre-dissolved in a bucket of water and pour in around the edge of the pool. Doses should be made at hourly intervals with the filter running.
