I also noticed today that the pump was a little choked up with debris and I
was only getting maybe 30% flow. I fixed this which dropped the water level
about an inch because of the added inflow. The auto filler kicked in
providing maybe 5-7% fresh water to the pond. When the pump gets choked up I
do get some muck on my riverbed. I cleaned the filter today (very dirty) and
will clean it again tomorrow and the next day if necessary. I've learned one
lesson... clean every week!

Thank you both for your replies. Where is the hydrogen sulfide coming from?
Rotting debris?

I suggest a clean out of the filter and a 10% to 15% water change.
.. right now!

You should not have a sewer smell in the pond.

somewhere there is hydrogen sulfide escaping, and that could be the
cause
of the dead
of a single fish. they are sucking around rocks or something and got a
big gill
full. do you have gravel on the bottom? have you mucked the bottom
out?
It should
not smell like a sewer, not good for the fish. ahhh.. do you have
aeration in there?

My wife and I notice a sewer smell when we get close to the water in
our
fish pond... as in bend over with our noses just over the water or when
we
get in there and stir things up. The plants and fish seem healthy, and
the
water is clear, although we found one dead fish today (out of about
20).
The
pond is about 1000 gallons (my estimate) and 3 yrs old with a
skimmer/pump/filter/auto filler set up. I must admit we haven't been
adding
the "aquaclear" bacteria powder or cleaning the filter very often
(about
once every 2 weeks). We have an overabundance of water hyacinth right
now
that we are thinning out.

Thanks,
