Trying to understand how the app handles impact of adding CYA to PH. Looking at my attached readings, Pool math is calling for me to add 545g of dry acid to lower ph from 7.8 to my target of 7.65.
It is also calling for me to add 293g of CYA to hit my CYA target. Adding that amount of CYA should also drop ph by -.1 according to Affects of Adding.
I assumed that would be factored in such that Pool math would call for less dry acid to account for the impact of the CYA its also recommending to add..
But it seems not. To validate this, I adjusted my CYA target in the app way upwards so that the app recommends adding tons of CYA, enough to completely drop PH to zero.. But the app still recommends to add the same amount of dry acid. So is each "box" in the app not taking into account what is being added in other boxes at the same time?
Sorry if that's not clear.
