thought i would chip in and let you comment on my effort so far.
Backgroung of display- 5 x 2 x 2 with 240 ltr sump containing skimmer (massively inefficient), DSB in display (silica play sand), approx 100 kgs live rock.
Most corals are 7 years old and all fish but 2 of the tangs, are of similar age.

I have always been interested in the algal screens as a method of saltwater maintenance but until now havent been enthused enough to try a proven method. Now is the time, mainly because my stock are requiring more and more good quality food stuffs.

I feed 5ish (santa monica food units) per day, plus a diy coral mush twice a week.
The screen is 13 inch by 6 inch. At the moment only 50% of the screen is lit, both sides by a single 23watt cfl each side. Gonna be putting lights on the other end of the fitting very soon. Flow is 2500lts hour.
