Actually, ours is precious close to the very bottom.

The pump is in the old septic tank, 7' down. The base of it's 5 gal bucket
is on bricks (3.5") above the very bottom. The pond has little mulm as the
koi sweep it around til it falls into the 'deep well/septic tank' and gets
pulled out. Heavy stuff is netted out of the deep well annually. The muck
goes into the veggie filters.

Very bottom...almost.

and not from the VERY bottom.. LOL, but yes it most certainly is the most
efficient
way of aerating, as long as the waterfall roils the water or the stream is
shallow.

What many of us are already doing surely competes well with 'flooming':
Think about the value of pulling water from the bottom of the pond,
running
it through a veggie filter and down a waterfall or stream...at a rate of
25-50% per hour. Massive exposure to air. Probably beats flooming hands
down!Jim
