How to Use BioGuard Lo ‘N Slo

Read entire label and use strictly in accordance with directions and precautionary statements.

Total alkalinity in pool water should be maintained in the range of 125-150 ppm. For pools using Mineral Springs® or pools equipped with chlorine generators total alkalinity should be 80-150 ppm. Pool pH should remain between 7.2 and 7.6 for the most effective use of chlorine. Test the pH using a reliable test method. If the test shows a pH above 7.6, then add this product to the pool water using the chart below as a guide.

Add this product when the pool is not in use. Broadcast product into the deep end with the pump and filter running. Never add more than 1.5 pounds of this product per 10,000 gallons of pool water at any one time. Allow the pool water to recirculate for two hours and retest the pH. Repeat treatment as necessary. Newly plastered pools may require frequent treatments for the first few weeks while the pool is “curing.” Do not add the product near metal fittings or allow the pH to drop below 7.2. Break up undissolved clumps of product that may remain on the bottom of the pool.

NOTE: SPECIAL INSTRUCTIONS FOR POOLS WITH COLORED PLASTER SURFACE: Do not add this product directly to pools with colored plaster surfaces.

CHOOSE ONE OF THE FOLLOWING METHODS FOR APPLICATION

Method 1

Pre-dissolve this product in a bucket of cool tap water, adding no more than 1 pound of product for each 3 gallons of water used for pre-dissolving. With circulation pump operating, pour the solution into the pool water in an area of strong circulation from a return fitting. Operate the circulation pump continuously for the next 8 hours.

Method 2

DO NOT USE THIS METHOD FOR POOLS WITH METAL PLUMBING, STAINLESS STEEL FILTER HOUSING OR METALLIC PUMP IMPELLERS. Remove all products from the skimmer. With the circulation pump operating, apply the appropriate dosage slowly into the skimmer. Apply at a rate no faster than 1 pound per minute. A slight increase in filter pressure may be observed, but is not cause for concern. Operate the circulation pump continuously for the next 24 hours.

DO NOT ADD ANY GRANULAR OR LIQUID PRODUCTS TO THE SKIMMER OF THE POOL DURING THIS 24 HOUR PERIOD.
