Cyano and LEDs?

[Enigma]

Woah! Just switched out my T5s with LEDs this morning, and the cyano outbreak I've been battling has become way worse in the last two hours. It is all over the place now, where as before it was limited to a few places on the sand bed.

Coincidence? Am I just seeing it more clearly now? Or, does cyano just really like LEDs?

Everything in the tank looks good, so I think my light setting are probably pretty close to what the tank's inhabitants are used to.
