I've read here that the pH reading is invalid when FC is high. How high is "high"??
Using the TF kit I get FC=23, CC=0, pH=7.2, TA=90. The pool is in its final recovery phase after the swamp event. Water is once again crystal clear.
I am not presently adding any chlorine but am monitoring with the FAS-DPD test every three days. The filter runs 8 hours at night.
I'm wondering now whether the pH is really that low or whether the test itself is influenced by the high FC. Since TA is at a good level I'm hesitant to mess with the chemistry just yet, you know?
