Exactly. Just build a large scrubber screen in a tank. You can easily fit 4000 square inches in a 36 tall X 96 long tank, and just attach the lights to the outside of the glass.
Well actually the algae will pick itself. Unlike plants, you don't put algae there for it to grow. Instead you start of with a blank plastic screen, and it fills in itself, based on growing conditions.the trouble with freshwater is finding a truly effective type of algae to form the filter screen with.
Now that's a new one. I have no idea.Maybe some sort of terrestrial moss would even be effective?

Just so I understand. Algae are a product of phosphates. The phosphates are in the water.
With your system one is simply giving the algae a place to grow which is more growth friendly to the algae ( screen and lighting ) and, admittedly, a more convenient system to clean the algae ( take the screen out and clean it and replace it ).
Basically, you are concentrating the algae growth in one " controllable " place.
But the system still is inside your tank's system therefore the phosphate containg water remains in your system and you are not getting the phosphates out.
So how does this "avoid/reduce" water changes?
Am I right?
