Hello all, first time pool owner here. We were swim ready Wednesday 6/21/17. It is now 3 days in, and we decided to check the levels to make sure all was well. I tried the AquaChek Free Chlorine tester and the test strip indicated 0 chlorine. I thought this can't be true, it has only been a few days since the salt was added to the pool. We added a 25 lbs of salt to the pool last night and this am I busted out the test tube kit (Oreq is the brand of the kit) and tested with the tube and again, the chlorine is zero. I am under the assumption that that is all we have to do to get the chlorine up in the pool. PH level shows to be high at between 7.8 and 8.2 so we conducted the acid demand test and found that 4 drops got it to the correct levels, meaning adding 1 qt of acid (however the testing tips card says no more than 1 pint per 10000 gallons). Total alkalinity was right at 150 ppm. Any advice would be much appreciated.
