Me again, I had my water testing at a pool place with a liquid test kit and they said my problem is my TDS is 3500 ppm and should be 1500 and that I
should replace some of the water til it is down to 1500 or lower, but my water is still crystal clear and the ph, alk, total chlorine is ok, just still no
free chlorine ?

Then I talked to the place that installed my pool and they say the TDS
is not high ?
