Anytime under a year cyno is more likely to break out. The tank is still cycling.
IMO, Chemi-clean and productls like it are just a band-aid and don't cure the problem. High water flow, low nutrients (Make sure you are not overfeeding), high CA, low phosphates are what you need in the long run. If you do elect to use Chemi-clean or red out etc, be careful. Speaking from experience, it can have an adverse effect.
