    Default I'm killing cyano with light

    Isn't that the weirdest thing?

    I just upgraded from my 4 bulb T5 to a higher quality 6 bulb T5 fixture (which I love by the way - no regrets about the extra expense now that I have it).
    I only got it a couple of days ago but it's wiped out the cyano I had on my sandbed (mostly low flow areas where I target fed the mandarins)
    The red is gone. Little bubbles are rising from the sand and leaving behind just white sand. So something is obviously being metabolized very quickly.

    I always just heard cyano happens when there's not enough flow -in fact I have a couple of Seio Superflows on order just for that.
    But I didn't change anything other than the light!

    Why/How would that get rid of cyano?
