Never seen algae grow but in standing water.

That may be the first tidbit you've mentioned, that held some truth to it.

I'm no pro but I had some stuff that I thought was an algael [sp] scum for
awhile till I stopped water at nite and watered less than other areas, and
got some yearly aeration, now its as good as it gets. there is a lot of
clay in that area too.
