TA 80-90*
CA 30
Temp. 78
Pool water is clear and everything looks good. When I opened the pool the TA was 70 so I brought it up to 80-90* (I have a problem with this test because I'm not sure if it is called 'red' when it actually pink....in the past I would keep adding drops to see if it would turn red but only got a deeper pink so now I stop testing as soon as the tube turns clear pink and add no drops to deepen the shade of pink so TA may be much higher); PH was only 6.8 so added borax to raise to 7.2 because I understand that liquid shock (12.5%) will raise PH so I didn't aim for 7.4-7.5. (**this is another test I have a problem with, once it goes above 7.5 I can't determine where it's at, it's never the top color that to me looks like it has more of a rose color but my solution just looks red.....I may have a touch of color blindness ?). Anyway, to bring it down, I used current 8 goal 7.5 and added 35 oz. of 34.6% MA. That worked but brought my TA down to 60-70 so I 'think' I added 16-20 oz. baking soda slurry in front of return jet yesterday. I waited several hours and got the current readings. I don't know how to bring the ph down without bringing the TA down again. Thus, the yoyo. Also, is there a test for PH other than the daily test like there is for chlorine?
