Hello everyone. This summer has been a challenge with the pool. Had mustard algae once two years ago; last year, no problem at all. This year, I've had three bouts of it. First one in early summer, followed the directions and slammed, up to 30 on chlorine, brushed and cleaned; all good. A few months later here it comes again. Repeated process and as soon as the FC got back to 6, here it came again.
Slammed to 30 one more time and kept FC level at 7.5-8. My local pool guy who helps sometimes thinks that's WAY too high, will seriously/quickly degrade the liner. He also says that if the mustard algae keeps coming back that I should dump half the water and refill, and probably change the filter sand out completely next spring.
What say you wonderful pool geniuses?
Thanks in advance.
