Pool vs Pond

BV, if I had the *slightest* idea of how to explain barometric pressure, I
would. Unfortunately, I can't. But maybe someone else can . . . How it works
is something else: as the bubbles rise, they displace the water. New water
moves in to replace the air bubbles, and pulls the "stuff" with it, drawing
it more towards the drain. The oxygen benefits of the air diffuser is pretty
much self explanatory. Folks that had regular covered bottom drains and
upgraded to the "air domes" swear by them.

Now, if you put an air dome on it, you
literally change the barometric pressure on the bottom; the rising air
bubbles assist in pulling the crud to the drain. And the air bubbles add
extra oxygen to the water and give the koi additional play areas.

I am still baffled by the air bubble thing. Can you explain further?

So the bubbles don't go into the drain, they surface above it. That makes
sense...not sure I want my pond constantly bubbling though.

The constant bubbles are what makes it GOOD! Extra O2, keeps your pond
ice-free, fishies like to swim through them . . . FWIW, if it disturbs the
surface too much when you want to watch them, get one of those remote
control switches (I have a slew of them I use for outside Christmas lights)
and plug your air pump into one. Then you can just flick a switch to turn it
off/on for viewing ease.
