Hello,
I have a 24000 gallon salt water vinyl liner pool with a chlorine generator. I just added some baking soda to increase my alkalinity and I am asking myself why. My levels are as follows:
salt 3000 ppm
pH 7.7
alk 50 ppm
free chlorine 3.5 ppm
cya < 20 (I will be bringing that up shortly)
The thing is, my pH just doesn't change much. If anything it tends to the high side of the acceptable range. The bicarbonate is going to shift the equilibrium to a higher pH and I am not sure I want that. Isn't chlorine more effective at a lower pH, say 7.4 than it is at 7.8?
