Progress finally, or The TA battle...

[steveinaz]

Ok, after multiple slams of acid this evening (and thanks to my waterfall for aeration) I've made serious progress in the battle of the high TA. Some numbers:

FC=5.5ppm
CC=0ppm
pH=7.5 (before slamming to 7.1)
CYA=90ppm (oops...updated reading tonight after 5 days of circulation)
TA=120ppm (uncorrected for CYA)...down from 180ppm 8 days ago
TA=93ppm (corrected for CYA, 30% factor)
CH=710ppm (yeah, yeah, I know. This is a battle for another day)

My grandmonkies will help me via "splashout" on the over-shoot of CYA, this weekend...plus, I have one of those pools that mysteriously looses CYA over the winter, so I'm not too concerned about it. I did up my SWCG output to 75% to compensate, which usually puts me at 6-8ppm FC this time of year.

QUESTION EVAN:
Should I be looking at corrected TA for my target of 80ppm, or uncorrected? Uncorrected would make my target 110ppm TA...

I was gonna slam it one more time with acid this evening, but a 7.0-7.1 pH made me wait until tommorrow. I should be golden after that. Oh, and...the snowflakes are gone.
