Does FC dissipate faster per unit time the higher your FC level is above the target FC in the Chlorine/CYA table? I'm trying to see if I'll have to use more chemicals if I add chlorine less frequently, but at higher doses.
For example, my pool has a CYA of 50 ppm right now. According to the table, the target FC level is 6 ppm. If I wanted to overshoot this target so I wouldn't have to add chlorine so frequently, will this result in a faster loss in FC per day than if I simply got it to the 6 ppm target? I would assume that FC dissipation would be faster since the FC/CYA ratio would be higher than optimal (11.5%) since there would be less available CYA "sites" for the FC to bind to, but am unsure as to how much faster. Any chemists in the house?
Another (extreme) example: is there an issue to simply raising the FC to shock level and repeat once the FC drops below the target FC?
Does anyone who plots his/her pool chemistry history see any noticeable increase in dissipation at higher FC levels for the same CYA level? A good place to look at is when you had to shock your pool with something that doesn't have CYA in it (e.g., liquid chlorine) and see if the slope of the FC vs. time plot is higher at higher FC levels. I just started the TFPC method and data logging, so don't have enough data to draw conclusions.
I understand it's a good practice to check the levels every (other) day and adjust accordingly, but am curious about the science as well.
