You seem to have the obvious covered. Aeration and a clean bottom. So your
next move is take a water sample, let it come to room temperature and check
the ammonia, nitrite, pH & Kh levels and any other tests kits you have, run
them and see if there is an ominous answer there.

I can't even see my fish today. Snow came in, screens covered, I went out
and could hear the water still flowing. So all's well, she said hopefully.
Times like this my ponds will be completely ice free under that snow cover.

Help please!
Just noticed my fish are near the surface of the pond (12 foot by 8 x 2 fot
deep) - I have the pumprunning 24/7 and have a small waterfall for aeration.
The fish are not gasping - seem perfectly OK, but normally I'd expect them
to be at the bottom when it's cold (last night it was about 1C minimum.
There is not much debris in the pond (newly created this year) and the water
is quite clear.
Should I be concerned about the fish?
I've had fish for quite a few years (biggest are 12inches).
Thanks for any info.
