If he can solve it without chemicals , then more power to him. I tried everything for months and couldn't get it out. I have a 200 gal
reef tank loaded with inverts, zoo's, softies and sps
, I used the chemical and the cyano
was gone in a week with not one iota of harm to anything else. For a newbie, a difficult problem like cyano
can chase them out of the hobby, which is why I recommended using the red slime remover. I hate to put anything in my tanks also. but that was the only thing that worked for me.
