Worked great for 3-4 days, NOT 90...
Followed directions to a tee - mustard algae on walls disappeared for about 3-4 days, NOT the 90 or even a week for that matter. Now I wonder if algae only disappeared bc I brushed it (w my stainless brush) off my pool walls... Says it supposed to treat ALL types of algae - but certainly didn't perform as advertised for me. Even tried extra phosphate remover after the fact - nope... & that's also w 2 floaters with 3-4, 3" tablets in each. Just cannot find ANYTHING that permanently removes this stupid yellow/ brown looking algae all over my walls (though my water is always sparkling clear) I refuse to swim in mustard algae, so now wondering if pool better off drained - even in this brutal 112 degree summer weather
HIGHLY DISAPPOINTED - thought this stuff would do as advertised for the higher price...
