Algae powder for Daphnia, etc.

Just a note from the "competition"-
No green water here either.
I keep clear containers on south & south-west facing windowsills and top up with used tank water. One container is crystal clear water with algae on the bottom & sides and what I THINK are rotifers? swimming around. The other container is also crystal clear except for the luscious stand of hair algae!
Maybe we need dirtier tank water!
I have been keeping a small culture of moina since March, in a clear plastic kritter keeper. No air. Just a couple strands of java moss. Feeding crushed flake food. Siphon out some bottom gunk with airline tubing, skim the surface crud, & top off with conditioned tap water on no schedule.
I think you have to trick the eggs into thinking it's spring, so they'll hatch.
