Newer to pool ownership and starting to take control of my own pool rather than using a service. I have been testing my water with the k2006 test kit and have the following question. Routinely I find that the FC, TA, CYA and CH are out of the recommended ranges however the pool is crystal clear and the CSI is balanced at -0.17. Certainly I understand the need to get the FC in control however do I need to be concerned about the others if the pool is balanced? Any help would be greatly appreciated. Thanks.
