This should be able to handle the following amounts of daily feeding:
1 frozen cube per day (2-sided screen), or
1/2 frozen cube per day (1-sided screen), or
10 pinches of flake food per day (2-sided screen), or
5 pinches of flake food per day (1-sided screen), or
10 square inches (60 sq cm) of nori per day (2-sided screen), or
5 square inches (30 sq cm) of nori per day (1-sided screen), or
0.1 dry ounce (2.8 grams) of pellet food per day (2-sided screen), or
0.05 dry ounce (1.4 grams) of pellet food per day (1-sided screen)

I'll be honest, this thread makes me feel like this...
Im really struggling to get my head round it all, it kind of seems overly complicated (I know its all well calculated).
For a waterfall ATS...
Can someone confirm for 2 frozen cubes per day I will need a 1 sided screen of 48 square inches with 24 watts of LEDs all on the same side?
Then if I lit the same screen from both sides 12 watts each side it would take 4 cubes per day?
What happens when I want to increase the number of fish or the amount I feed?
What if my screen is over sized? say 72 square inches lit from one side?
48" square inch sized screen would only be about 7"x7" which seems tiny compared to the ATS's people have made.
