HOW TO USE: Do not pre-mix this product before adding it to your pool. Only add this product directly to your pool or skimmer. Use entire contents when opened.  If any granules settle to the bottom of the pool use brush to disperse.

Method for dosing directly into pool: Add the required dosage of this product during evening hours while the filter pump is running. When adding this product to your pool, broadcast the product evenly over a wide area in the deepest part of the pool. If any granules settle to the bottom of the pool, use a brush to disperse.

Method for skimmer addition: Use this method to avoid bleaching vinyl liner or paint. Make sure the filter pump is on and properly recirculating through skimmer. Empty skimmer of all chemicals and/or debris. Contamination may cause an explosion or the release of toxic gases. Do not use this method when an automatic chemical dispensing device (e.g. feeder) is present. Pour this product slowly into skimmer, making sure the material is drawn into the system at the same rate; do not allow this material to accumulate as toxic gases may be generated.

WATER BALANCE: For best product performance, swimmer comfort and crystal clear water, maintain pH in the 7.2-7.6 range.  Maintain total alkalinity in the 60-120 parts per million (ppm). Maintain calcium hardness above 200 ppm.  Use a reliable test kit that measures all these ranges. Use TropiClear to make adjustments. Follow label directions for each product.

Reentry into treated pools is prohibited above levels of 4 ppm due to risk of bodily harm.

OPENING YOUR POOL: For best results, see the “WATER BALANCE” section above before treatment. Always ad-just and maintain pH in the 7.2 to 7.6 range. Follow “SHOCK TREATMENT” directions on this package. Allow 30 minutes for product to disperse. Test free available chlorine with a pool test kit. Repeat treatment as needed.

SHOCK TREATMENT / SUPERCHLORINATION: For best results, see “WATER BALANCE” and “HOW TO USE” section above before treatment. Every 7 days, or as necessary to prevent pool problems, shock treat / super chlorinate the pool by adding 1 bag of this product per 10,000 gallons of water to provide 5-10 ppm available chlorine. Additional shock treatment is required to correct problems which are caused by visible algae, high bathing loads, heavy wind and rainstorms. Additional shock treatment is required to correct problems such as unpleasant odors and eye irritation. Check the available chlorine with a suitable test kit.

ALGAE CONTROL: Follow “SHOCK TREATMENT” directions on this label. Add this product as close as possible to any algae on the sides or bottom of the pool. If necessary, repeat the treatment. To prevent possible staining or bleaching, take the following steps immediately after treatment: Thoroughly clean pool by brushing surface of algae growth, vacuum and cycle through filter.

For preventative algae control, use your preferred TropiClear algaecide product regularly. Follow label directions on the algaecide.
