And there was one person in front of me an older guy and he was purchasing like 10 bags of shock. Not sure all what he has put in there, but he asked the person is it ok to add two more. Then he was like I have put the phosphate stuff in there and something else and did not listen to much after that as he was leaving. He talked about he had backwashed and put in new DE and something else I didnt hear. As he was leaving she said bring your water back in so we can see how it is. I also heard him say I checked the cholorine and there is none in there. I am guessing he was using test strips to test.
Then I purchase my polaris screen basket for the connector to the wall and then there was a guy behind me that bought two packets of shock as well.
I was just shaking my head and wanted to talk to both of them, but just let them go.
