How important is it to get TA down to 90 before adding Borax to water. We have very soft water here and I don't think I've ever been able to get it past 120 ever! I just bought some PVC and installed the eye's from the pool on the end of them 1-2' above water. Have 3 of them in a 20x40 pool. Ta started at 220 yesterday, took pH to 7.0 turned pump on 24/7 and 24 hours later pH up to 7.5 and TA 180. So, 3 more days maybe??

My current readings are:
Borate 15 From last year.
Is it really important to get that TA down to 70-90 before I bring Borate up to 50? I'm sure your answer will be yes, however, when I run some hypothetical numbers in the pool calculator with TA at 200 it still shows "balanced" as long as pH stays around 7.2-7.8.
