From Ingrid's post on veggie filters:
"It needs to be only 8-12" deep so it doesnt go anaerobic."

Won't it go back to aerobic if bouncing over the waterfall rocks?

Depends on how many birds you intend to kill with one stone. I use two 55
gal drums, those are about 4ft tall, this setup lets me have a bio filter,
settling chamber and veggie filter all in one enclosure.

Also consider what kind of plants you intend to keep in the bio filter, and
what their preferred depth is. Remember you can always raise the pots by
placing them on bricks, upside down pots, etc, but you can't make a water
filter deeper.

My VF is in two sections. One section is less then a foot deep, and the
other is a bowl shape that goes down to about 18 inches. This is part by
design, part by newbie mistake. Someday I plan on tearing it all out and
redoing it, but for now it works great.

This depth makes it easy to clean, and maximizes the root mass to water mass
ration. I get very good fallout using this setup.

BV.

I have an initial sketch of how the VF would
fit into my pond system.

the water bouncing over yes and that is fine for water moving over rocks. I guess I
dont think it needs to be any deeper. and my waterfall doesnt go over rocks. Ingrid

It is not whether the water will change going over the waterfall, but the
action of the type of bacteria, and the waste products produced. Aerobic
digestion does not produce hydrogen sulfide or methane which smell bad and
are toxic to the fish.

So how would a 4 or 5 foot deep veggie filter be created to not have
this happen?

those gases are light and quickly dissipate if the water is going over a waterfall
with lots of rocks. I doubt it would be toxic at that point. but it does smell bad
while in the veggie filter. I just dont know why anybody would make it deep when
shallow does great. Ingrid
