Cant do the math

[bingocaller]

So I have been reading and reading but still having a bit of trouble :?:

If I am running a 250 liters system then:

How big does the plate have to be if I am running it with lights on both sides? In cm would be nice

How many Liters of water does the flow have to be pr hour if I am running a 250 L system dualsided?

Thanks!

Tank Size Guideline:

0.5 actual (not equivalent) fluorescent watts per gallon MINIMUM [0.13 watts per liter].

1.0 actual (not equivalent) fluorescent watts per gallon for HIGH filtering [0.26 watts per liter].

1.0 square inches of screen per gallon, with bulbs on BOTH sides (10 x 10 = 100 square inches = 100 gal) [1.64 square cm per liter]

2.0 square inches of screen per gallon, if vertical but lit on just ONE side. [3.28 square cm per liter]

4.0 square inches of screen per gallon, if HORIZONTAL [6.56 square cm per liter].

1.5 actual (not equivalent) fluorescent watts per gallon if HORIZONTAL [0.4 watts per liter].

18 hours of lights ON, and 6 hours of lights OFF, each day.

Flow is 24 hours, and is at least 35 gph per inch of width of screen, EVEN IF one sided [60 lph per cm].

Very rough screen made of roughed-up-like-a-cactus plastic canvas.




Feeding Guidline:

Each cube of frozen food you feed per day needs 12 square inches of screen, with a light on both sides totaling 12 watts. Thus a nano that is fed one cube a day would need a screen 3 X 4 inches with a 6 watt bulb on each side. A larger tank that is fed 10 cubes a day would need a screen 10 X 12 inches with 60 watts of light on each side. If you feed flake, feeder fish, or anything else, you will need to blend it up super thick, strain out the excess water, pour it into a cube, and see how many cubes it is.

if you ave 250L.
the your screen shuold measure forexambel 22cm(L)x19cm(H)=418square cm.
the flow should 22cm(L)x60L/t= 1320L/t
