Just filled our new AGP Sunday night, got the SWG working & tested the water yesterday afternoon with the cover on using the Taylor Basic kit & the FC was at 2. Had it covered until this morning when I ran the Intex AWG 6 hrs, which would have shutdown 2.5 hrs ago. Now the test is showing completely clear, no FC. We never added CYA, thought we'd try just going by the directions on the SWG of running the SWG longer without CYA. I now see that's not possible. So now what do I do? Run the SWG another 6 hrs & add CYA now? Afraid that might not be enough...
