I have had green water and now its clear using clear pond. I have had long
string algae running from my waterfall and got rid of that using SAB. But I
still have a fine green algae that clings mostly to the bottom rocks and
lies floating in clumps along the bottom. I scraped up a leaf bag full of
the stuff. What type of Algae is it and what can I use to get rid of it?.
Obviously clear pond and SAB do not work. Pond is 7000 gal with few fish,
plenty of anarcharis and 5 waterlillies
