I haven't posted here for a while because the information on this site is so thorough and accurate that I rarely have needed to ask questions. But, now I'm up against a lee shore.
We are having a wedding at our house this coming weekend for my daughter, with 100+ folks coming from all over, which includes a wedding pool party. Now, an outbreak of mustard algae (powdery when brushed, vibrant yellow/green in streaks and spots) - normal shock didn't eradicate it; got it up to MA level for 24 hrs, then MA coming back after chlorine coming down, even though CC has been non-detectable.
I still need to clean out the pool light cavity; but the main question is: should a sand filter be able to filter out dead mustard algae? The sand filter has worked fine in the past, but it seems to be letting MA (or dead MA) through, since streaks of deposits are settling downstream of the shallow end return, and the pressure is not increasing, which it usually does quite a bit after running the vacuum.
Any helpful suggestions are greatly welcome. Only 5 days til WD (Wedding Day)!
