I understand that the chemical you used was successful, but how long has it been since you used it? Has any of the
cyano returned? It is my understanding that, unless the causes of the
cyano is not addressed, chemicals are simply a temporary solution.

In my own experience it took many months to finaly get the stuff removed. And the chemicals only provided temporary relief. I simply tried all the usual suggestions until the problem finally went away. In order of importance,
IMO, here they are:
1. Water Changes (which included manual removal of the
cyano via syphon) to get the
phosphates down to undetectable
2. Increased water circualtion (powerheads - your new best friends)
3. Reduced lighting duration (including letting the tank stay dark for a few days, if needed - it works!)
4. Reduced feedings (they won't starve)
5. New light bulbs (if your's are old)
There are many more items that I'm certain I have forgotten. The big thing is that, in most cases, to win the battle against
cyano is usually a long term affair. For those who have had success with the various chemical solutions ... congrads. They simply didn't work for me. Hope this helps.
