BioGuard Burnout 73 is a superchlorinator for swimming pools. With the highest percentage of calcium hypochlorite of all the BioGuard shocks this one bag treats 16,500 gallons of water making it one of the strongest shocks on the market.
1 lb per 16,500 gallons of water.
Note: Never add water to product. Always add product to large quantities of water to fully dissolve. Maintain operation of your pump and filter. Treatment should be done at night or during a period when the pool is not in use. This product can be added by broadcasting the dry granules over the surface of the water at the deepest end of the pool while the pump is running.
Shock Treatment / Superchlorination:
Adjust pH between 7.2 and 7.4 prior to shocking or superchlorination. Add this product at night or when the pool is not in use. To prevent pool water problems, shock at least once per week during periods of heavy use or when water temperatures are above 80 degrees Fahrenheit and once every two weeks in resident pool receiving normal usage. Maintain operation of the pump and filter. Do not enter the pool until the free chlorine residual has dropped to 4.0 ppm or less as measured using a suitable test kit. Between treatments with this product, continue to maintain the proper water balance and sanitizer level in your pool as recommended on the label of your normal pool sanitizer.

Products arrived ahead of schedule and was exactly as described!!! Thank you for the excellent service!! Highly recommend!
I've been buying pool chemicals from Pool Geek for 7 years and have never been disappointed in any way. Fast shipping and the fact that the website tells me how many of any item is in stock and if / when restock shipments are expected lest me try to plan in advance as much as I can (in southern IL) where the weather can be, lets say questionable, is great. I Highly recommend you try Pool Geek. They'll send your preferred brand of pool chemicals to your front door. It's that easy for me.
