Cyano and LEDs?

And, being that I use dry rock (the equivalent of a phophate bomb), I think the issue is compounded. I think that issue is mostly resolved by this point, as the "new tank" gha disappeared from the new rock about mid-August (I think).

According to is article (which is actually an article for planted FW tanks)
http://www.aquascapingworld.com/alga...=Cyanobacteria the spectrum cyano thrives in is 530-620 nm. The corresponds very well with the cool whites in the Sols.

I'm thinking that I just need to keep the whites off, and that a bit of blue and royal blue won't be particularly detrimental.
