I am getting ready to add Borates to my pool. I would also like to lower my TA a bit more as part of the process. I am concerned that the addition of a working SWG will cause my PH to rise more quickly than I want.
I know that adding the Borax will raise the TA as well currently I'm at a TA of 80 and I'm thinking I want to be about 60 but that's just a guess. I've added a new SWG this year and I'm learning about how it changes PH on the fly... but only have a couple of weeks so far. Water is still cold, but the Solar heater is bringing it up to swimming temp slowly.
I have a spa jet that fits into a return that I can use for aeration. Pool math tells me that reducing the PH from 7.6 to 7.0 will lower the TA by 11. I'll have to do that twice to hit my goal of 60+/-.
The question I have is does anyone know how long will it take to get the PH back up from 7.0 to 7.6 using the spa jet. It creates a nice small bubble plume in the pool so I'm hopeful the process won't be long.
I'm not looking for hard and fast numbers but more of an approximation from experience. Am I looking at a 2 day process, 10 days, ??? days?
Current numbers are
