A follow up to my own message is that emergent plants work better than algae
in freshwater and bald cypress planted in plain sand so they have to soak up
nutrients from the water column work the best along with water tupelo which
has roots that emerge from all long the part of the trunk that is under water
making the trunk look like a duster mop.
