That’s the tilting i can’t seem to keep the TA down either. I will get it to around 110 then the next week week I test TA and it’s already back up to 120/130. It’s like the pool wants to be 120. However the oldI haven't been following your thread each day, but as Dave noted above, the TA will eventually begin to fall lower with repetitive use of acid. As the TA falls, your rate of pH increase should also slow down. Remember that new plaster work and aeration can cause pH to rise. Fresh water from the hose can influence TA/pH as well. I would think that once your TA gets down to about 70-80, your pH should stabilize much better.
I blame things on the wife all the time when she's not looking. Its okay. Our little TFP secret. As for the testing, any of it, if you have questions, just let us know. We'll coach you through any of them if they seem odd or inconsistent. Anything you do at home is still better than going to the store. Have a good evening.Either I am as bad at testing as the store or my wife is messing with me and adding baking soda after I add acid, lol.
Good to know I am not the only one! I am going to test PH again tomorrow and see where it jumps. Then will check TA on Saturday when I usually do the pool cleaning and chem checks. I am just confused on if I should be testing PH every few days and lowering or once a week and if I need to push the TA down. I have a friend with a similar pool and he only checks his PH weekly and he is usually in the same range as me and has to add roughly the same amount. I don’t want to over think it but I also don’t want to let it get out of control. I really appreciate all the help, the new kit is a little more tricky but I am seeing that it may be more reliable then my old. Following the TA directions is pretty important with the new one and my old was pretty straight forward. Learning curve.I blame things on the wife all the time when she's not looking. Its okay.

Simply keep your pH in the 7's range. Bring it down to around 7.4 or so when it reaches into the 8's.I am just confused on if I should be testing PH every few days and lowering or once a week and if I need to push the TA down.
It’s usually in the 8s about 2 days after bringing it down so it looks like I will be adding a few times a week to keep it at bay. That works I felt it was simple until it started jumping up but weather changes making things move so just have to change up my tacticsSimply keep your pH in the 7's range.

Leave your TA alone for now......it's really that simple
I can add maybe twice a week. Probably equal out to about same amount a week or maybe less. That make sense on the CYA test. Around 70 at a glance it is hard to see unless I look hard for it so originally I called it 70 but could see the outline as I studied it. So I added a little more got to middle of 60-70 and knew not to call 65 so figured 60. Then retested and got closer to 50. So glancing I would call it probably 70 when it is pretty much gone. This will help for sure.Is it possible you could test your FC and pH during the week? I suspect if you could add MA twice per week, your TA will come down some. That is the number you want to get to 80 ppm or less to keep your SWCG from creating scale.
My suggestion on the CYA (use your 60 reading for now):
When you do the CYA test, try this next time.
Once you have your solution ready, back to the sun, etc. Fill the vial to a line, say 80, lower the vial to your waist level and glance for the dot, you see it, add solution to the 70 line, glance, see it, repeat until you no longer see it with a glance. Then use the CYA value one step above the line you read. So if you stopped at 50, use 60 ppm CYA.
The vial is in logarithmic scale. So it is not viable to interpolate between the lines. Just use the whole numbers, such as 50, 40, 30, ....
