This should be no problem, in a place like Davie. Even here, in the frigid north, there are lots of ponds that are full of Anacharis, Cabomba, Hornwort, and some Sagitarias. Primitive plants, like algae, use the same nutrients as higher level plants, and compete for these nutrients, so once you get an established, healthy crop of desireable plants growing, you should have less of an algae problem.
