This and dinos isnt a good mix. Sorry to hear that. I saw this before with another r2r member. Not sure how that turned out. It's kind of a tough one really. Because, you can cure chrysophytes but it would possibly increase dinos. Actually the procedure could cure dinos too? Lol the member did a chemiclean treatment after getting rid of chrysos and THEN the dinos flourished. You willing to beat chrysos and see what happens to dinos? You'll get a lot of cyano but if you let it grow(to an extent), eventually it will go away.
