We are not allowed any. You must have coliform before you can have E-Coli. This means that all water circulates through the filter system in the time stated. Although we do heat our pools some at the beginning of the season to take off the chill of the water, we do not continue this past the middle of June. Some patrons complain but I explain to them that this is a safety issue.
Chlorine is more effective in colder water.
Once our pool temperature hits 78 degrees we turn off the heaters. We super shock all pools at least once a week. Although our park may not be as pretty and have beautiful buildings with great landscaping as others, we choose to provide safety first and aesthetics in the future. Our park has an excellent safety record that we strive to maintain. Below are the Microbac test results.
