Does FC deplete daily at the same rate regardless of its level? I have a CYA of about 80 (used to be 100 so I drained 14" out to get it to 80). I have been keeping the FC level around a 10. I lose about 4ppm/day here in Houston and this requires me to add about 1/2 gal of 10% liquid bleach/ day in the summer. If my CYA was 50 and I could then lower my FC to the chart level of 7 would I still need to add 1/2 gal daily? Does the FC burn off at the same rate regardless of the CYA and FC level? I've done the overnight test and I am well within the acceptable limits and my water looks clearer than ever. Thanks.
