I just purchased a new home and this is my first pool to play with. I had a local company come and open the pool for me on Wednesday the 11th. They told me not to touch the pool for the first week, just let the filter run 24x7. Well, my TFT test kit came yesterday, the 14th, so I decided to check the chlorine level...0. I went and picked up some tablets and put 3 tablets in each of the two skimmer baskets as it said on the directions. About 45 min later I figured I would check the CYA level. Using the TFT kit I got about 3/4 of the way to 100 and couldnt see the block dot.
Where do I go from here? Should I test again later on to see if that wasn't just a fluke test? Are those levels high enough where I actually need to start replacing water or should I just try and deal with it?
