It is not deep enough to over winter fish, you don't need to run a pump in
the winter, unless you have it very close to the surface to keep an air hole
open. but looking at the pics it does not look deep enough, don't add
anymore fish, maybe take out some rocks from bottom just to give the fish
more space. You will have to do a very good clean up in the spring because
having rocks on the bottom will collect a lot of crap and will not be good
for the fish. you can use a bubbler only if you see your fish gasping at the
surface, this will be hopefully caused from the water being to warm as there
is no shade, othwise no don't waste time or money.
it does look great though, good job.

Any ideas to make our set up better? We just use plain pumps 2 to the top
falls and one to the lower features that goes through a UV light. We do
sometime fight algae. In the winter we just run one pump stright in to
the pond. Could we us a air pump / bubbler instead? You can see what we
have at the following web page.
