HOW TO ADD CHEMICALS: There are two ways to add chemicals. You must read the instructions on the label and determine if the chemical needs to be DILUTED in a bucket of water and then added to the pool or BROADCAST directly into the pool from the packaging. Again, keep in mind that you can only add "X"-amount of a chemical per 10,000 gallons of water AT ONE TIME. If the amount that you need to add is higher than the maximum amount (per 10,000 gallons) that can be added at one time, the chemical must be added in increments, allowing at least 6 hours between additions.
