wild algae update

Update on my local wild filamentous algae. I tried to harvest some local wild algae a week or so ago. My attempt was premature as the algae has not matured enough yet to get much algae. I find that the old growth that went thru the winter freeze cycle is still there, but is rotting and of no use. It has broken loose from the bottom and is floating about the ponds and lakes. It has a thin veneer of bright green new growth on top that is misleading; giving the illusion that the entire matts of algae are harvestable, when in fact there is little there but a mass of fragile, dead, rotting plant matter .   I see that in my house algae tanks that recieve morning sun, the new algae is growing rapidly. An algae tank that was formerly receiving morning sun and was very productive, but now has the sun blocked by a window shade, is several inches deep in dead plant matter with no regrowth apparant. I am observing that the wild algae does not seem to require full sunlight to flourish, tho that is only an observation, not backed up by scientific testing of the effects of various light levels on the algae. http://www.cleantick.com/users/larryhagedon/blogs/wild-algae-update
