    Lighting the sump

    I want to grow chaeto in my sump. I have some "throw-away" lights that came with my 55g, which I have replaced with comps that now supply around 5.5 wpg. If I use my throw aways on the sump, I would obtain about 2 wpg. Would this be enough to grow the microalgae that I want, or am I going to need to buy a new light? I actually have one more throw away that would bring things to 3 wpg, but I am running out of room to fit cheapo lights for my chaeto

    The actual number is 2.4wpg. I know that's not much -- but I am trying to go bare bones as the sump lighting couldn't matter less to me.

    I have a 9watt 6500K PC over my 20 gal sump. I have mangrove pods and two kinds of macro growing with no issues.

    Super!

    So I should have more than enough light.

    What are your favorite plants for the sump? I'd like to really use plants as a nutient absorbtion so that I can all but eliminate algae.
