This is a vinyl liner pool with a TA60 Pac Fab sand filter system. The sand is about two years old in the filter.
The liner was installed last July.
I have been adding 182 oz. of bleach each evening (6% sodium hypochlorite), HTH brand Super algae guard which does have ammonium in it. This has been my daily program for about 10 days.

I used to use trichorl 3" tabs before switching to bleach about mid June.

Once I figured out it was some kind of algae, the pool store here gave me a bottle of Banish and that did not even touch it. After that I used Yellow Out. That seemed to lighten the algae a little but after a couple of days the staining came back. I then tried the Yellow Out a second time. I also threw in a bottle Algaecide 60 from IN THE SWIM.
Probably have been using good much algaecide.

I did drop a puck on the surface and the algae burned off under and around it. But in a day or two you could see the algae covering the area again.

Before I started adding the algaecide, whenever I brushed nothing happened. You could brush and brush and there was no noticeable change and didn't look like there was anything to vaccum up but you could daily see the algae staining spreading.

Any help is appreciated. Thanks.
