I've never tried coral snow so I can't comment, but mb7 can fuel the cyano and make it grow more rampant. That was the case for me when I added it but definately cut down on feeding and do more frequent waterchanges. Also you could add vinegar as a carbon source to outcompete the cyano. Just google vinegar dosing to see how. But if you do decide to do vinegar dosing start very slow as you don't want to crash your tank by overdosing....
