Hello,
I have a 18 x 33 oval pool with a Hayward 23" sand filter 1.5 hp. I use the pool frog tender with minerals and my filter system isn't sand but the filtra balls.
Last year we only used the pool a few times, but it remained clear. This year it started off great with clear water, but after two weeks of hot weather we developed mustard algae.
Our Chlorine level remained 0.5 pp as suggested by the frog mineral system, but our hardness was low. I have been having difficulty keeping up the hardness for some reason.
Well we developed mustard algae. We shocked the heck out of it, washed the walls twice, cleaned all of the equipment, even spent $$$ on new filtra balls. BTW when we emptied the hayward filtra tank it was brown water. Pretty gross. Now we have fine dead gray algae masses at the bottom of the pool which we keep trying to vacuum up but the stuff is like fine powder. My husband is vacuuming to waste and we are running our system almost 24/7. But each day more settles to the bottom. I was told we can't use flocculant or clarifier with the mineral system so how do we get this up? When can we swim again?
Our chemicals are regulated except we have a high chlorine level which we were told to maintain to make sure all of the algae dies. Water is crystal clear except when trying to vacuum it up and it stirs about.
Any help would be greatly appreciated.
