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.

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

drop in an airstone. surprisingly enough, the only luck I have had over wintering
water plants is when the water was aerated. Ingrid

Maybe because deep is available whereas shallow isn't?

The key design measurement for a VF is not depth but surface area. You need
to maximize your surface are in order to maximize the number of plants you
can float in it. More plants, more roots, more cleaning. A five foot deep VF
is probably no more prone to going aenerobic then an 2 foot deep one, but
over time you are more likely to clean the 2 footer then you are the 5
footer. Once signifigant mulm builds up, then you start having the aenerobic
problem. What I am saying is that it is not the depth that causes the
problem it's the depth causing you to not clean it that causes the problem.

Beside what would be the value of a 5 foot deep VF?

Mine is deeper because I wanted it to drain into my raised
pond.
I guess I could have just filled in the bottom with dirt but
I was running out of dirt ;-).

Oh sure, I am not saying it's bad...just that for filtration it's not
neccessary. Biomechanical filters need volume, VF's need surface area.
