Generally, the OCLT is done at shock level.
rechecked sunup this morning with TF100, heavy rain yesterday most of day-
FC- 4.5
CC- 0
TA- 70
CH- 250
CYA- 50
PH- 7.5
But, the minimum FC with CYA of 50 is 4, not 3. The 4 to 8 is the FC range suggested by PoolMath.I've always been using these Pool School recommended levels-
FC 3 to 7
PH 7.5 to 7.8
TA 70 to 90+
CH 250 to 350
CYA 30 to 50
which begs the question- why and FC of 8?
This is the correct RANGE of suggested #'s, based on surface type. The FC is based on the CYA. 4 FC is minimum for 50 CYA.the target levels I posted are from the Pool School chemical levels based on surface type http://www.troublefreepool.com/conte...mmended-levels
if these are incorrect, what levels should I be using?
