I've had intermittent yellow streaks/smudges along the North facing wall of our pool for years. I tried to convince myself that it was discoloration of the plaster, and would scrub with brushes, stainless steel brushes and a pumice stone. I would keep the FC around 4 minimum, 6 after adding bleach each evening. This year I finally faced the truth: Yellow/mustard algae!
When it showed up in May, I SLAMed to yellow/mustard levels (around 24) for several days. Passed the OCLT, clear water, streaks on the wall gone. Since then I have maintained FC at min 6, target 8. No more algae.
Recent tests: FC: 8, CC: 0; CYA: 35-40; TA: 80.
My costs for bleach and acid are double what they have been in the prior 25 years, keeping the FC level at yellow/mustard recommended levels.
My question: do I need to manage the pool as if I have Yellow/mustard algae FOREVER?
Thanks
