Thanks Don for finishing up this post. I had typed out a similar answer to your first paragraph on P & N but must had had a senior moment and did not actually post it. That's twice this week

Mike I questioned the ID as many mis-ID it. Many seem to think that if they see a "algae" with lots air bubbles it is Dino's and if it has no or few air bubbles it is cyano or diatoms and that is often not the case. As Don pointed out it is how and where they feed. Dino's are by far more common in high flow areas and cyano in low flow areas. A method from contolling cyano is as Don as stated, high flow and moving the flow around. With Dino's either high pH with Kalk or high Mg++.

I have no doubt that I've had both growing in my tank, and I'm sure I've mis-ID'd them from time to time as well But whenever I get a bloom of anything, I almost always see it in the high flow areas of the tank first, it seems to make little difference in my tank what it is in particular that is blooming. But yes, I'm in total agreement that good flow is helpful when dealing with cyano, or any annoying microorgainism like it.
