So, I am trying to understand how the loss occurs. From what I have read here, the CYA protects from loss from UV exposure by binding to some fraction of the chlorine, the "excess" so to say is available for the killing of nasties and oxidizing organics. But I have also read that loss will happen due to evaporation, etc and that will be a certain proportion of the total chlorine in the pool rather than a particular umber of ppms, which is why you don't want to overshoot much the target level. I suppose all of this is also dependent on the surface area exposed (which explains why covers should help) and temperature, etc
I would like to figure out a reasonably close to optimal plan for my cya levels and the dosing given that I can really only test or add things at most once per day. If someone could explain the loss mechanism in some detail it would be very helpful. I want to figure out whether a cover makes sense and by how much to overshoot if I am going to be away for a day or two. Or maybe whether I should just go with a SWG ...
And I haven't done any chemistry since high school, Maybe I shouldn't say it, but I pretty much hated chemistry and now I am paying the consequences.
