Pool opened 5 days ago. Didn't clear after 2 days so hit it with another 5 gallons of liquid 12.5 chlorine. Chlorine level way high but now normal. Put robot in to clean tiwice and yesterday and today some of the kids have black marks on the bottom of their feet?????
All my readings are fine with the taylor test kit. Don't notice any algae or what I saw they call algae when I searched for a photo of it online.
