In my experience, once you've rid yourself of it, it doesn't come back. Correct the issue and, if it's a new tank, let your biological filter mature. It took about two months for this in my current system. I hated looking at my tank the entire time and dreaded all the work that went into it, but, now the only algea problem I have is all the macro that I grow in my fuge and I haven't seen a hint of cyano.
