Welcome to the forum!
This forum is focused on pool owner management of residential pools. Be aware that your public pool is likely required to use much different parameters than those shown on this forum.
I suggest you read through Pool Care Basics - Trouble Free Pool and even look at a few of our videos TFP-TV - Trouble Free Pool
