I am new to this site, and have had a pool for 9 years and have always gone to the pool stores. I have a hard time keeping FC and they say I don't need FC. I just bought a TF100 test kit, and tested my water.
FC .5, CC 2.5, TC 3, CH 225, TA 200, CYA is 55. What should I do to get my FC up (where should I keep my FC) and my CC down? My pool is nice and clear.
