Dead algae.. dos that reduce oxy levels?

My greenwater finally died off, ...

By itself?

Does the dead algae reduce oxygen levels?

Aerobic bacteria suck down oxygen like no tomorrow.

Do you circulate your bottom water?

If not, leave that bubbler on all the time.

Yep. I suspect lots of overcast rainy days, and increasing the number of
plats to it.

And, um, Aerobi means?

Nope. At least I haven't.

If not, leave that bubbler on all the time.

Will do.

Air-breathing. Your pond is alive with them, they break down
waste. But they need oxygen to live.

Will do.

The bubbler forms a small current, moving water from the bottom
of the pond to the top. The top of your pond aerates the water
very well, but the bottom of your pond is very low in oxygen.
So you move the low oxygen bottom water to the top, it gets
oxygenated.

The air bubbler itself adds a little oxygen also, but really
plays second string to the circulation/top of your pond thing.

Some folks pull water out of the bottom of their pond, pump
it to a waterfall or something.

A well designed pond will often have two pumps. One to power
the skimmer (to get floaters off the top), and one to circulate
lower water, to oxygenate the pond.

You don't really need a bubbler, if you have the right set up,
but it will work okay if you don't.

How big is your pond, how many gallons per hour is your current
pump?

ah, ok.

Not sure of the exact size, but it's 13x13x, 1.5-3 feet deep.

The spitter is a 2-3 foot tall gargoyle, and it pulls from the homeade
plastic milk carton furnace filter I built from recommendations here.
(Though it doesn't seem to be doing much of a job at all of removing the
floating dead algae.)

This is the first time I've ever seen the fish all together doing the gaping
thing.. maybe it's some common group behaviour as well?

Okay, I'll assume an average depth of 2.25 feet. Your pond is
13 x 13 x 2.25 x 7.48 = 3,160 gallons.

Hrm. A "spitter" is your only water flow? That doesn't sound like
it could be very much...

You should move about 3,000 gallons of water per hour. I'd look
into a Sequence 750. Lots of gallons moved, low watts consumed.

Almost always means not enough oxygen in the water.

Here's a pic link to give you an idea.. the gargoyle can be lifted by 1
person, but it's easier with 2. For scale, the large boulder to the right
cannot be lifted or budged at all... it is about 4-5 ft square, and the
sundial near the spitted is a foot tall, maybe a tad higher. Our old
Christmas tree behind the pond stands about 7-8 ft at the top tip.

Nice pond, but I think Courageous is right. You need much more water flow.
My puddle is only 500 imperial gallons and I have about 1500 gph split
between the water fall and the fountain.

"Courageous" did the calculations and came up with:

Okay, I'll assume an average depth of 2.25 feet. Your pond is
13 x 13 x 2.25 x 7.48 = 3,160 gallons.

Having done my own figuring and fellow ponder's figuring of their own ponds
and then running a water meter, or salt calculator, we've found all to be
off by 20-50%. All those folds, curves and I wouldn't be surprised plant
containers (if it is an older pond) take up space.

So with the math and the picture above I'm betting she has something over
2,000 gallons, and the only way that little filter is gonna work is to mass
plant the pond. My lily pond of 1,000 gallons has 12 water lilies, 2 lotus,
4 baskets of iris, 2 baskets of arrowhead, 1 lizard tail and a few water
hyacinths, plus bunches of anacharis.

It looks like you have the starts of a water fall to the right? Do you have
anyone mechanically inclined to help you do an out-of-the-pond filter
perhaps? I'm thinking plumbing similar to what my guys did for me (see
diagram on webpage under *My Filter*) where you go over the side and use
siphon effect. www.jjspond.us ~ jan
