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 especially useful for pool owners who want a dependable chlorine shock for weekly maintenance, hot weather, heavy pool use, cloudy water, or times when the pool needs a stronger oxidizing treatment.

Before applying, test and balance pool water. Adjust pH to the recommended range before shocking, keep the pump and filter running during application, and apply the product at night or when the pool is not in use. Do not swim until the free chlorine residual has dropped to 4 ppm or less, as confirmed by a suitable pool test kit.

How to Use

Routine Shock Treatment

Apply BioGuard Burnout 73 at a rate of 1 lb per 16,500 gallons of pool water. Broadcast the granules evenly over the deep end of the pool while the pump is running. Continue circulating the water after application so the treatment can disperse throughout the pool.

When to Shock

Use as part of routine pool care, especially after heavy swimmer use, high temperatures, rain, cloudy water, or visible loss of sparkle. For best results, apply at night or when the pool is not in use.

Important Safety Notes

Never add water directly to this product. If pre-dissolving is required by the product label, always add product to a large amount of water, never water to product. Do not mix with other chemicals. Do not enter the pool until the free chlorine level has dropped to 4 ppm or less. Always read and follow the product label before use.
