As well as the basic algae scrubber, which worked fine but I was always safety conscious about splashing salt water! I was lucky enough to be given a pre made unit by a fellow forum member, for which I used warm white cfl bulbs to light the screen. 2x 9w bulbs on either side gave some good growth, but unfortunately I did not document it so well for my own personal use. I placed all of my pictures on a forum, which is no longer running, whoops. The build is below, you will see that I modified some bits of cardboard to prevent light from leaking out and being more direct on the screen.

I had many ideas of making my own algae scrubber from acrylic and using leds. 660nm was decided to be the best wavelength for great growth, so I experimented with some 3W. I also planned and had a acrylic unit made up, but it was never used in anger due to being too big for the new aquarium I was to purchase.

Looking at this design now, it isn't too different to the one I purchased and am currently using!
