We set up our algal turf scrubber 2 weeks ago. It might actually be working. The algal colonies have gone through a progression from what may have been a bright blue/green to a more mature hair algae growth. It seems to be bringing nitrates down because they dropped from 20 to 5-10 since last week with no water change. (You go algae!) I think between skimming the precursors of nitrates and the algae removing them, we could be on to something. If anyone is interested, I'll try to post a picture.
