I just received the report shown in the photo for testing my pool water. The lab simply said that the results were acceptable under the current State regs. I have these tests done once a month. I would like to know if an HPC of 4 is considered a low level of bacteria? I looked it up and it looks like the maximum allowable is 100 MPN/ml. I really don’t know how to read these reports. Any help would be appreciated. This is an indoor pool with FC around 3.0. ORP of 750 plus or minus.
