How to prevent algae growth on Drosera media

[shawnintland]

I'm not sure of the names, but that's okay as I have soooo many different kinds of algae growing I'm thinking of opening an algae museum! I'll try to remember to take some pictures. I use straight chopped sphagnum for my neps seedlings and it's odd that some trays are filled w/ algae and others barely have any. Nowdays though, since all the 105 cell trays are in two hydro tables, it seems everything is getting it. I have about 8 trays of 105 cells ea that the algae smothered the surface and killed off any hope I had for all the different Drosera seeds I planted. Bummer. Still had a few hundred make it but disappointing compared to the planting effort involved!
I did follow David's instructions regarding the sand top-up and have removed the misters from one table and changed to bottom watering system. I'll see how it all looks when I get back from Borneo.
