without getting into too much backstory (because it's confusing and i'm stupid for thinking pool store tests were ever valid to begin with): is it even possible for TA to drop from 85 to 22 in a matter of two weeks with just 3 acid additions over that time period?
long story short: i'm just now trying to take over maintenance and control of my pool, been working at it for about a month now. ordering my taylor test kit today (this is another addition to the part about me being stupid and not having just ordered it when i started). i also have a waterguru sense that i bought and installed based on the positive reviews of some here and elsewhere. over the past week i've been using the WG to tell me when to add acid to maintain my ph, i've been taking the water to the pool store multiple times a week early on to test the rest of the chemistry.
first pool store test said my TA was 0. added baking soda and took it back, up to 120. steadily came down over the next few weeks: 98, 92, 85. today was the first time i decided to take the water back to the store and have it checked again, since the WG has been telling me when to add acid. today's pool store TA reading: 22.
now, i did add a bit much acid yesterday...the WG told me my ph was 7.8, so in my trying to bring it down to 7.5 i actually added too much acid and brought it down to 7.3. this is the third time i had added acid over the past two weeks (which was the last pool store test, which again measured TA at 85).
so my question is three fold - main question for this thread is: is it even possible for TA to drop from 85 to 22 just by adding acid to maintain the ph over a two week time period, even if i might have overshot the acid target yesterday by a little?
and second: which kit is the best kit for me to get? i've been struggling to decide / understand the differences between the K-2005 and K-2006 and SALT versions, and want to make sure i get this right for both the amount of money spent and my pool's sake...
and third: should i assume the pool store test is right and add baking soda? or should i do nothing and wait until i get my own kit and test it myself? should i worry that having a low TA for a few days until my kit comes in will cause any issues?
feel free to hammer me with any questions and/or tell me i'm stupid (i already know i should have just started with the test kit lol)
