I need an ID on this algae it is brown and only covers my sand. I vacuumed it out during my water change 2 days ago and now it is back again. Any suggestions on how to get rid of it would be appreciated. All parameters are in check. Nitrate 3-5 ppm with salifert and po4 0.01 on Hanna checker. Sorry about the photobomb I can't take a picture without her in it today.
