You would probably need to do some loose math on it but this gives you the basics
for how much it drops it. Actually it's quite a bit.
But all that dead space up there is to me only good if you plan lots of stem plants
and hope they don't quite make it to the top of the water. Might also put in a Y shaped
branch/w one long side laying on the bottom making the other part come close to
and then along the surface...well maybe like 14" up from the bottom and putting
some fern like Java Fern up towards the end/w the roots dangling under the limb.
OR...you can(cuts the light less but not much less) leave the top 4" without water
and allow one or more pieces of the driftwood to stick up out of the water.
Baby Tear(not dwarf) grow tiny leaves when emersed and will grow if wrapped
around such a piece just under the top of the water.
