    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.

    You have an algae bloom caused by excessive nitrates. Do you have any
    water plants planted in your pond? The more plants you have, the lower the
    concentration of nitrates you will have in your pond. Also, you can add
    beneficial bacteria and enzymes to the water that, once established, will
    out-compete the algae for nutrients and help keep the water clear. You can
    obtain this product at just about any fish dealer or garden shop. And yes,
    you should clean out your filters periodically and do periodic small water
    changes. This should help, but at this point in time, it will take time to
    clear it up.

    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 fill my veggie filter with fast growing plants such as pickerel weed,
    iris, parrots feather and wherever there's space, a few water lettuce. My
    VF acts as a settling tank also, catching a large amount of "crud" or mulm
    as the water goes past the plant roots. By the time they die back in fall,
    the pumps and filters are about already to be turned off for the winter.

    my two main plants are water celery and cyperus. in winter I drag the
    cyperus into the basement and put it in a tank under a light. the
    celery I start new every year by digging little plants up that
    volunteer next to the pond. wash the roots, stick them in the veggie
    filter. in winter I just run a bucket filter, the water lily stays
    green and the algae comes back. Ingrid

    I am a newbie at ponding, but I just HAVE to share this because I also had the green cloudy water develop over the last few months in my pond, and could barely see my few goldfish. I decided to go at it yesterday and today I have a CLEAR POND again!!! I cleaned the two filter pads. I added Tetra Pond Water Clarifier according to directions after removing as much of the floating debris as possible. I cut and trimmed any dead or old greenery that was touching the water. Then I had to figure out how to get the gunk off of the majority of the flexible liner, (I know there is a lot of controversy over this issue, so I have been allowing about half of it to remain and try to remove half on a regular basis.) Well I looked around the house and found a long 6' handled painting roller brush handle and new soft roller. I used that to wipe the bottom of the pond that had so much gunk buildup. Then the Tetra Pond Water Clarifier caused clumps to form which I removed again with the paint roller! I am excited because today the pond is back to being clear! YAY! ---I was so happy because the product also worked the way it was advertised! ;)
