How much Shock and Swim can I add to a 8′ by 30" vinyl pool? And, do I run the filter after adding Shock and Swim?


A one pound bag is designed to treat up to 10,000 gallons. Therefore, 1/4 of a bag or less should do it for you as you probably have just over 1000 gallons. And you definitely want to run the filter in order for the chemical dosage to properly mix.
