Hi Ingrid,

I have 6 fish left (they are only babies), on the bottom (its a preformed
pond) is the pump and the large clump of Oxygenators and also 4 small clumps
of oxygenators, one in each corner. The rest of the plants are on ledges.

The temperature of the water on Saturday was about 70 degrees. the sun only
shines on the pond from about 14:00-19:00 approximately.

I was under the illusion that Oxygenators only made Oxygen and didn't
consume it and in the posts where people talk about gasping fish that was
because they didn't have Oxygenators in their ponds.

Even if the plants are using the oxygen at night I still have my waterfall
which runs 24hrs a day.

Sorry Kathy and Jan -I did read your posts but your questions were a bit too
technical for me to answer -I did find your tips very useful though and did
not feed the fish at all today.

breeders of fish make green water for their fry. green water is actually
healthier
than gin clear water when a pond is first filled. fish can go for a month
without
food, but in green water they got a lot to eat.
you have a 250 gallon pond with how many fish?
what is on the bottom of this pond? it sounds like there might have been
some
anaerobic fermentation going on and a release of hydrogen sulfide.
what is the temperature of your water? all those plants and algae are
making oxygen
during the day, but using it up at night. it doesnt sound like you have
supplemental
oxygenation in the pond. this could result in the death of the largest
fish from
lack of oxygen. no, not possible to have too much oxygen

The other day I noticed a huge underwater disturbance and stared at it
for
ages trying to work out what was causing it -its hundreds of air bubbles
they seem to be causing a swell of some kind under the surface.When I
first
put my fish in, everytime I went near them they hid under the pump and
they
looked all squashed and uncomfortable so after speaking to the guy at the
pond shop he got about 20 oxygenators tied then together and when I got
home
I weighted them with a rock and put them in the centre of the pond for
them
to hid in -they loved it as soon it as soon as they saw it.
Now of course it has grown and seems to be creating lots of oxygen -is it
possible to have too much O2 in a pond?

My pond is 1000 litres and has a waterfall at one end, 6 small clumps of
oxygenators scattered around the sides and on shelves, the huge clump in
the
middle, a large waterlilly with about 12 pads at the opposite end from
the
waterfall, 7 marginals on the shelves and 6 floating plants which are
multiplying faster than rabbits.

The dead fish looked in perfect condition by the way -no signs of
sickness
maybe the Green water has worried it to death because it could not see
the
sun anymore?
