My ideal TA level should be 70-90

9/21/09
TA 60
Added chemicals to increase TA, TA Target 80

9/23/09
TA 90 (yet Targeted 80)

10/13/09, 22 days after adding chemicals to increase TA
TA 70
Borates 50
Temperature 68

I leave TA alone for now, right? Or do I increase it & target 80 or 90?
If it matters, I hope to close in the next 2-3 weeks, awaiting ideal water temperature (& completion of a deck caulking project not yet started, also awaiting ideal weather conditions)

CYA question
On 6/28/09, almost 3 months ago:
CYA: 20, was super close to 30 (68 days prior it was 40 & a week before that it was 40-50 & the weeks prior to that were 30-40).
Is testing CYA again indicated? FC & CC remain fine.


Thanks

Your numbers look fine to me especially if you are getting ready to close soon and the FC is steady.
