Hi maknwar,
What kind of algae is occurring low in the tank? In my experience, cyanobacteria (blue-green algae) can be combated with water movement but if it is any of the old green standbys (dust, green dust, etc.), I would look more toward your fertilization regime than water movement. Also, is the tank new? I always get weird algae problems in new tanks, but things tend to stabilize after a few weeks. Good luck!
