I started noticing a brown/green layer in the pool in a few areas such as ledges and a few areas on the wall. The water appeared to be clear. Once it was brushed and vacuumed obviously the water would get cloudy. This started 3 or 4 days ago. I have replaced the cartridge filter with my clean backup. Vacuuming as ofetn as possible.
Test results as follows:
FC 5, CC 0.5
PH 7.8, I know this is a little high been adding baking soda to get TA up to 80
Wtr temp 81
5/15, 10AM, just prior to pump starting
FC 4, CC 0.5
Shut off SWG
I added 116oz of bleach just for precautions.
FC 10, CC 0.5 at 12N
FC 6 at 630PM, pump is off normal.
Gonna wait till sun is off of pool and test FC to start the OCLT
