So I been reading a about borates and speculating whether I should use or not. I also have a few questions.
1. Based on what I read, I think the cost of MA won't change much since you will eventually use it to lower PH in higher doses. Using borates will only help to adjust in big doses instead of many smaller ones over the season. Is this assumption correct.
2. Based on the numbers on pool math, in order to have a favorable CSI during winter, the PH (and TA) needs to be high.
If these numbers don't go up gradually over the end of summer, how do you get these high. For reference these are my numbers
PH = 7.6
TA=110 ( I been trying to reduce it, but I also prefer to keep my pool cover closed)
CH = 325
Temp = 81 F
CYA = 40 (its working fine since I have a pool cover and pool usage is mostly towards the evening)
FC=4
SALT = 3400 ( from taylor drop test kit)
Borates =0 ( not tested, but I never added them)
If I reduce my TA to 60, I have to maintain PH at 7.7 to 7.8 for CSI to be between -0.3 to 0
But during winter, water temperature drops to 55 to 60F, which means my TA has to go up to atleast 80 to maintain a favorable CSI. There is not much of wiggle room to adjust the PH. Enlighten me if I am not looking at this properly. I do not want to end up in a situation where the CSI moves below -0.3 without much wiggle room to adjust.
How can I adjust the TA come winter ?
