Okay, so I'm curious. Has anyone here actually worked at a pool store. I'm curious because I took my tests and then took them into a pool store. Everyone here is saying your own testing is more accurate, but I'm not sure..."why". Here are my readings followed by the pool store:
Water Temp: 63
Pool Store tests:
They ran all tests in like a total of 30 secs. The reason I am asking is that my builder requires monthly faxes from a pool store showing that I am caring for my pool appropriately and will not accept mine unless I am "certified". Are all of the pool store guys really "certified"?
