Product Details
Compatibility and Requirements
BioGuard Burnout 73 is made for swimming pool shock treatment and is suitable for all pool types when used as directed. It is a good fit for pool owners who need a strong, fast-acting chlorine shock to help restore water clarity after heavy pool use, warm weather, rain, or visible dullness.
For best results, balance pool water before treatment. Adjust pH to the recommended range before shocking, operate the pump and filter during application, and apply the product at night or when the pool is not in use. Do not re-enter the pool until the free chlorine residual has dropped to 4 ppm or less, as confirmed by a reliable pool water test kit.
How to Use
Routine Shock Treatment
Use 1 lb of BioGuard Burnout 73 per 16,500 gallons of pool water. Broadcast the granules evenly over the deep end of the pool while the pump is running. Keep the pump and filter operating after application to circulate the treatment thoroughly.
Best Application Timing
Apply BioGuard Burnout 73 at night or during a period when the pool is not in use. This helps the chlorine shock work more effectively and gives the product time to circulate before swimming resumes.
Safety and Handling Notes
Never add water directly to this product. If dissolving is required by your label directions, always add product to a large amount of water, never water to product. Do not enter the pool until free chlorine has dropped to 4 ppm or less. Always read and follow the product label before use.
