Feeding 2 cuber per day and no water changes, for a horizontal scrubber can somebody please confirm my maths:

(Floating scrubber as in a piece of 7 count mesh floating in the sump, supported by egg crate possibly)

21 sq. inch for 1 cube 24 sq. inch for 2 cubes
24 sq. inch * 4 as its horizontal
96 sq. inch * 2 for no water changes
Total is 192 sq. inch

12W for 1 cube so 24W for 2 cubes * 1.5 fr horizontal = 36W. (all red 640nm 3W per LED)

Does this seem correct?
