i went through the same problems as you, both cyano and dino and also was very eager to "cure" the problem.
there will be Dino X for Dino. due to my stupidity, i overdose (too eager) and had all my corals wiped out over 1 week.
i would strongly recommend just using bacteria... special blend, microbac7, etc...
let nature take its course... have to be very very patient and let the tank mature, if not u'll burn out trying to solve all the problems.
