Hi all,
I've done a little searching but haven't found what I consider an answer for this... I have an inground vinyl liner pool. (17x35) Anyway, after opening I notice lots of streaks of this purple algea, it feels very sandy and for the most part brushes off and falls to the bottom.
I have super shocked it, scrubbed it, vacumned it up and repeated the process. I can see a few more stubborn spots but will get to them.
IS this purple stuff really BLACK ALGEA?
Purple, very sandy algea ???
Re: Purple, very sandy algea ???
Had a similar problem with my inground pebble-tec a couple of years ago. It was almost like a violet colored sand that formed on my vacuum hoses--only on the hoses (vinyl). I was perplexed also--searched the internet and couldn't find a thing. Someone finally told me it was COPPER! I've never seen anything to verify it, but I've made sure since then not to use algaecide of shock with copper in it, and it has gone away and never come back. Maybe this will help you--its probably worth a shot. Good luck.

Purple algae
I also have a purple sandlike residue in my inground pool. We've had this pool for 14 yrs and have never had this problem before. Can't seem to get rid of it. Is there anything to use to actually KILL it?
