Life got in the way these last couple of weeks and I ended up letting my pool go a bit. Bad timing, because it's springtime in Texas and with all the pollen and organics, it quickly got out of whack. A couple of days ago, I saw that one side of the pool had started getting a yellow green coat of algae. Due to time constraints I gave it a brushing and 3 gallons of 10% liquid chlorine to raise FC to shock levels.
Today I got to inspect the pool more carefully. The yellow green coat was back but brushed off easily. There was also some green algae spotting in various places. Here are the readings for my 30kgal pool:
pH: 8.4
FC: 0
CC: 0
TA: 90
CYA: 20
I have started a SLAM (unfortunately before checking pH, or I would have adjusted that to 7.3 first). Is it still OK to raise pH midway through the SLAM?
For one, CYA has been super low all winter. Would trichlor pucks be the best way to raise CYA to say 40 in my situation? Should I wait till after the SLAM to raise CYA?
What about the algae stains and spotting? Would brushing the walls be enough or should I do anything else besides the SLAM (backwash filter, clean behind lamps, etc.)
Thanks for reading and offering advice!
