Unless you address the reason it was there to begin with it will come back. Test your water parameters.

Cyano is actually a bacteria that thrives off of excess nutrients.
How much/often/what are you feeding?
How old are your bulbs?
How long do you run your lights?

The extra feeding may be part of your issue. I feed my tank every other day and sometimes skip a day. I have seen no ill effects.
I suppose, if the food is eaten within a quick period you should be ok...but, if you are seeing cyano, then you may be overfeeding....
