So after returning from a week vacation (tanks were maintained by LFS guy), one of my 16g has an outbreak of cyano and the other has serious dinoflagellates. I hit the google and plan to attack the dino by sand siphon, new chem-pure elite, remove CuC and 48 hr blackout. Ill get some red slime remover for the cyano. Assuming LFS guy just really enjoyed feeding my fishies. Any successful tips?
