Well, it's interesting.

I can tell you right now that the last time I had them I dumped an entire bottle each of the phosphate and nitrate supplement into the tank.

The dinos population EXPLODED. Doubled in size easily within one day.

But within about 5 days I started seeing green algae. That's the sign you're through dinos.

I have no idea if the dinos burned themselves out of something essential thanks to the sudden population growth or if some competitor algaes just started to take hold finally as a result of all those nutrients.

So, I believe the goal here is to be reasonably low nutrients, but try to keep your algae diversity. Don't ever go for complete extermination of your green film algae or anything. You want a little around.

Also, you know what else came roaring back? Coraline algae.
