Hi everyone --

Got my Taylor test kit today - here are the results from tonight...

pH = 8.0 (has been 7.5-7.6 with HTH kit for days)
Acid demand = 3 drops
FC = 6.4 (was 15 this morning with HTH kit)
CC = 1.0
TA = 125
CH = 700 (!??)
CYA = 60

Based on a CYA of 60, a FC of 6.4 would be right in the middle of the ideal range per the best guess CYA chart. Would that be high enough to throw the pH off, or is the 8.0 likely valid?
