If you are going to use air stones, then you will also need to have a
pump
to run the air stones. The small aquarium air pumps with the
appropriate
aquarium air stone is sufficient. If you were able to smell anaerobic
odors, then I would suspect that you have a layer of debris on the
bottom
that is several inches thick. If this is the case, you will need to
remove
that debris with a vacuum or fine net. A larger pump or an air stone
won't
do much to help with the problems associated with thick layers of
debris.
Before stirring up the layer of debris and releasing the hydrogen
sulfide
gas, which is very toxic to the fish, you need to add some potassium
permanganate to the pond to neutralize the H2S.
I checked but didn't find a layer of debris on the bottom - a very slight
film, but microns thick at best. What I do have is a carpet of lily roots
extending out from their baskets and exploring the pond bottom. Could
these
trap the gases and cause the odor? If so, how can I "clean up" a root
system?
Mind you, the odor isn't emanating from the pond, but only when I bring
something out of the water, like the hyacinths in my original post.
Anyway,
in my checking for debris I did stir up the bottom a bit - I hope I didn't
cause any toxicity problems.
That sounds normal to me. A small body of water with lots of life, will
definately have some odor when you are bent over it and stirring it up.
Certainly you should not be bowled over by stench, but some smell must be
normal.
