Bubbler pumps

about 30" deep. Any suggestions?

Tetra makes a "deep water" line of pumps, of which the smallest one
should work fine. By deep water, they mean a bit higher pressure for
tall tanks.

Use straight plastic tubing, running straight down so no water collects
(and freezes) in it. A straight pipe, straight down is the only thing
that has worked for me.

" so I was thinking about using the harder clear plastic this year. Any
input?

Hi Maureen - I am using the clear, less flexible line and have for ~8 yrs -
I have seen the more flexible latex line and decided the stiff line running
at a downward slope with no sagging loops was better as no moisture will
collect in the line - I have not had a freeze up yet, except for not
keeping the the ice dome build up broke open in ~15 F extended periods -
now I tap the ice dome to break it daily in real cold periods

breathing spot for the 7 goldies... I also used the blue flexible tubing
and
that got frozen down one year, the pond froze over and everything was
lost....

I don't use a bubbler at all. I use a smallish 100gph or so pump sitting in
the shallows of the pond. It moves the water in a small area just enough to
keep a nice hole in the ice.

If you are in a cold zone, like me, you may have trouble with any of
the aquarium pumps. The problem is that they are all diaphragm pumps
and when the diaphragm gets cold it stiffens and can not push the air
as deep as before.

I solved my problem by making my own PVC bubbler and connecting it to
my air compressor. The compressor is in the garage (detached) so the
noise is not an issue. Some think that running the compressor is more
costly than an aquarium pumps but I cranked the numbers and found it
to be cheaper to operate.

You don't need depth to keep the surface open.

Yeah I tried that one as well, but the air line freezes up along the
way.

I have had ice 18" thick and want my bubbler below that. Even with
the bubbler there has been a thin sheet of ice form in the hole during
really cold nights. I break that out by hand.

Have not had that problem yet. Do you have a moisture collector on
the output of your compressor?

I would take a watering can with hot tap water out to the pond, and use
that to un-freeze the opening. If there is open water, it will
evaporate, or be splashed out, so there is a need to fill up the pond.

No, they are not cheap.
