Excited to say I rec'd my TF100 test kit and tested last night. Must say... some of the results were pretty different from some of the test strips I was using.
Here's what I have:
FC 5 (have SWG, but it is not working... keeping chlorine levels by adding bleach while waiting on new SWG to arrive).
CYA appx 30-40 (need to add more)
Here's the problem:
TA 210, pH tested at the top at 8.2, so I'm not sure what it actually is.
I've been battling this ever since we filled the pool about a month ago. The last test strips I used seemed to indicate I had finally gotten TA and pH down into a more normal range, but the test kit showed otherwise (it did rain a bit, so I don't know if that could have affected it?).
Here's what I'm not sure about regarding the process for lowering TA:
I believe I can add a max of about 14 oz of dry acid at a time, but...
One brand I used before said to add directly to the pool... the brand I have now says to dilute in a bucket first... do I follow the package instructions, or do you have a different recommendation?
How long do I wait between adds?
How long do I wait to retest to determine the effect of that add?
Since I don't really know how high pH is over 8.2 (the test max), how do I know it's going down?
How many adds can I / should I do per day?
Pool school says the aerating can be done by splashing kids (sounds good to me)...
How long after an add can the kids get in?
Do I have to keep adding every day to keep making progress? In the past I tried adding once every couple days, but didn't seem to be getting ANYWHERE (could my TA have been THAT high originally)?
Should I add the CYA before beginning to add the dry acid to address the TA? If so, how long do I wait after adding the CYA before adding the dry acid?
BTW... water is clear and looks good...
Ok... sorry for so many questions... I feel like I understand the steps that need taken, but just can't quite understand the right timing of it all.
Thanks in advance for the help!
