Dinos gone...but what now?

[loweryphil]

So for the second time in 3 months, dinos have stopped blooming and my sand is white. High nutrients and algae starting also. Hears the problem, the first time after two weeks of it gone I thought great! And turned on my bio pellet reactor. The next day...boom back again.

This time I want them not to return. Is there anything I can do to prevent the return of them and bring nutrients down?
