Yep, I have to agree that learning to just let things settle down and find equilibrium is essential. I think I was almost too attentive in the early days of my RSM - picking algae off, measuring Calcium and Salinity every 10 minutes, etc., etc., - when all I really needed to do was wait. It seems inevitable that things will go a bit astray every now and again, but so long as you cover the basics its seems that most things will self-resolve. Cyano is particularly irritating though. One last thing - have you changed your charcoal recently? I've taken to doing mine once a month and it seems to make a positive difference.
