     Dave,
      Here in Va Beach, Va. we get a lot of what I call "Green Slime"
     algae. I am also aware of the darker sphagnum moss you are referring
     to. I have been able to control my algae by adding chopped up pine
     straw. I use a spice grinder and add some pine needles which has been
     cut into 1/2 inch pieces(approx), then I grind these pieces up into
     almost a power. I sprinkle this over the seedlings and algae and the
     seedlings love it, but the algae hates it. I been able to control
     about 98% of all algae this way. I have found out that the algae
     doesn't like the acid condition that the pinestraw creates. If the
     first application doesn't control the algae, try this method again.
     The only thing it does is benefit the seedlings. Remember, where these
     plants come from, the soil is nothing but broken down pine straw and
     sand. Hope this helps.
                                 Resp,
                             Charles Brewer

I have some S. leucophylla seeds that are sprouting in peat/sand mix that 
has
lots of algae swarming around, both on top of the mix and in the
standing water that the plants' pot sits in.  Some seeds are also sprouting
on live sphagnum, which is a darker green than normal -- probably from 
algae.
Outside, I wouldn't mind, but this is happening under lights in my house.
I would like to get rid of the algae without getting rid of the seedlings.
Any suggestions?
David
