To lower or not to lower.....

[KineKilla]

So, my levels have been acceptable so far this year (at least I think they're OK). The two things that are way off and don't appear to be changing are my CYA and my high TA levels. I have added CYA in both liquid and granular forms but it has not yet been a week so testing is futile...in fact I still have 2 socks full dissolving as we speak.

So my question now is regarding the high TA. I read herehttp://www.troublefreepool.com/content/129-how-to-lower-lowering-total-alkalinity. That it isn't necessary to lower the TA and that it's actually discouraged to do it just for the sake of doing it. So is it something I should bring down or not?

My tests from the last 2 nights (seem pretty stable to me)

Yesterday:
Salt 3000ppm
FC 2
CC 0
PH 7.4
TA 130
CYA 0 - <30

Tonight:

Salt 3400 (finally up to where I want it)
FC 3
CC 0
TA 150 (why is this climbing? Maybe CYA adds TA?)
PH 7.2
CH 200

Water temp is 68

CYA does add some TA. The only reason to actively lower the TA is if your pH is climbing faster than you like.

It appears that my PH is dropping rather than increasing... But that's only one night. I'm also still tweaking my pump schedule and chlorination a bit until I get it just right.

The CYA is also slightly acidic.

Hmmm, strange how something can be both Alkaline and Acidic at the same time...
