hi all, i have a well established pond, had it for about 12 years now,
it measures 14ft by 9ft by 4ft deep and holds about 3145 gallons i have
two large filter boxes, a uv clarifier and a submersible pump which
shifts about 3000 gallons an hour it also has two smaller pumps
powering two waterfalls. the fish i have in it are koi, goldfish, orfe,
2 barbel and 2 catfish. we used to have really clear water but the last
2 years in late summer the water has turned very green and cloudy and
has a lot of particles in it. the pump is checked twice a day for
blockages. about 3 years ago the goldfish had babies, about 20 of them
and when they grew to a reasonable size i gave all but 2 of them away.
i dont think the pond is overstocked, all the fish seem perfectly
healthy but this cloudy water is driving us nuts. has anyone any idea
what might be causing it ? my partner insists each year that we empty
the filter boxes out and clean the media and the water does improve but
i'm sure by doing this we upset the biological balance of the filter and
as i'm now suffering from arthritus it's also becoming a pain in the
backside each year. if anyones got any suggetions on why this is
hapening and how to stop it i'd be grateful.
Are you doing water changes? Like the other said, nitrates, water changes
should be done once/week 10%. In your currently state I'd do them every
other day till the water clears up.
What are your water parameters? Ammonia, Nitrites, pH & KH? ~ jan

i have quite a few plants in the pond, 4 lillies, parrots feather, canadian pondweed, various iris, mimulus and a few water soldiers. i haven't done a water test for ages and i'm due a water change soon. i will also get the filter media cleaned as soon as poss. can someone give me some info on veggie filters, what plants do you have in them and what do you do in winter when the plants die back. thanks.
