Not yet. When FC is above 10, the pH test reads falsely high. Check out the pictures in Accurate pH test during shock levels with R-007?Sunday 8AM
FC 10.5
CC .5
PH 8.0
Working on reducing PH, did a acid demand test and came up with 4 drops, Taylor test kit chart calls for 4.62 Lbs of Sodium Bisulfate (dry acid) or 1.72 Qt of Muriatic Acid.
I have a 5lb container of PH Down Sodium Bisulfate, should I just go with that to reduce PH?

FC 4.5
CC .5
PH 8.0
TA 90
CH 190
CYA less than 30
CYA is still unreadable using the Taylor K-2600C as the lowest reading is 30 and I can still see the black dot when the tube is full. For SLAM purposes I will use a CYA of 30 and shock to 12. Will be checking FC/CC every 2 hrs today and do a OCLT tomorrow morning before I head off to work.
