Thnaks so much for following me on this difficult journey. This morning my FC was 21.5 (still lost 2.5 ppm overnight). I vacuumed to waste this morn and then added 2 more bottles of bleach. I didn't test again until after sundown and it was 23ppm, so I didn't add anymore bleach. My best guess would be that I lost 3.5 ppm during the daylight hours. My CC stayed consistent at .5 ppm last night, this morn, and this evening. My water is still green, but a lighter shade of green. Just when I really get down in the dumps about this, you say something encouraging and I become hopeful again. Thanks for the support, AnnaK and CarlD. I will keep up the good fight. I hope it won't be too much longer. My grandkids (I have 19 total, ranging in age from 19 to 1 yr old) are so dissapointed that they can't swim @ grandma's. Today I took 6 of them to the creek to play in the water and explore.
