I noticed some of this on the floor of my above ground pool i thought it was dirt but when i wiped it up it had a slimy texture, it was more green in color so i assumed it was regular algae i scrubbed, shocked and did use algaecide (on Monday) yesterday the pool looked good aside from a thin greenish film on top of the water, i skimmed it , let the water circulated well, let the pump run all night and today everything looks great but i saw a few small patches of this stuff again!! Is this actually mustard algae??
Oh we have a salt water pool and a sand filter, sand was replaced this season.
