Hi All,
I have been SLAMming for a week to deal with a mustard algae outbreak and am getting inconsistent results. The pool has been clear for a few days, but chlorine usage is inconsistent. For example, last night before bed I had
FC: 28
CC: 2
PH: 7.6
TA: 90
CYA 70
In the morning I had
FC: 27.5
CC:2
I added a gallon of 12.5% bleach and tested a couple hours later (pool in sun):
FC: 28
CC: 0
I then tested this evening and had:
FC: 22
CC: 2.5 (kids went swimming for an hour could that cause this much CC? Other days with no swimmer load also have had CC go up)
Questions:
Why didn't FC or CC drop overnight? I would've expected the FC to burn off the CC. If living algae were still present, I would've expected FC to drop.
Could algae still be growing at these FC levels and still causing CC?
