rubber maid container is out of question as i only have 4" xtra space between the wall of my stand and the 30 gal tank. if i will add another tank as a fuge [in the near future] i will have to consider the possibility of making another kind of stand and maybe hiding it there, but it really doens't fit my living room.
anyhow...i tried to do some math and eher is what i came up with.
in case of blackout... (48x18x2)/231 = 7.48 gal will flow back to sump.
in sump i will need to leave (36x13x4)/231=8.11 gal or 4" from the top. this means that the highest divider i can have is 12".
that leaves me with:
17" of fuge which comes out to be 10.5 gal [ i know its not enough but its a start, besides im planning to keep using my eheim 2213]
9" of skimmer area, or 5.5 gal
and 6" for mag12, or 3.72 gal.
i left 4" for dividers. 2"on the skimmer side, 2" on the fuge side.
im gonna try to put this into a drawing maybe tomorow. tell me if i got anything wrong!!!! plz
the dimensions inside my stand will be 13"x40" +/- 1/8"
