    I have tried everything to get rid of my green water and algae, but nothing
    is working.
    My pond is not overstocked, I am not overfeeding and I have copious
    quantities of plants.

    Today a friend brought round a test kit and these are my results.

    pH 8.6
    Ammonia NH3/NH4+ 0.0ppm
    Nitrate N03- 10ppm
    Nitrite N02- 0.0ppm

    I see the pH is too high, but what do these results show? How do I lower
    the pH?

    What else can I do?

    Is this a liner pond? Have you done any mortar or recent cement work?

    Do you know what the KH/buffering is? If you don't have a kit, and don't
    have easy access to getting one, take a pH reading at dawn & dusk (or as
    near as possible to those times).

    Take a measurement out of the tap, aerate for an hour. Check the pH & KH.
    If the pH & KH numbers are good, do 20% water changes every other day for
    about 4-5 times. ~ jan

    Are you using a UV light?

    In news:, DCLong scribbled:
    Yes. It has a new bulb and sleeve to make sure it is working correctly.

    Liner pond with no recent cement work. However we have been suffering awful
    rainfall. Copious quantites requiring water to be removed from the pond to
    stop overflowing.

    Ordered a test kit and will post as soon as it arrives.

    If having heavy rain, more than likely your buffering is zip. While waiting
    for test kit, I suggest adding 1 cup of baking soda per 1000 gallons. This
    will not increase a pH over 8.4 already. It will stabilize it. Some say it
    will bring a high pH down, but it never worked for me, and I used 4
    lbs/1000 gallons at the time. ~ jan

    your nitrates are pretty high for a pond not overstocked.
    what is your hardness?
    rain water should drop the pH, so your well water probably is loaded
    with calcium.
    try shading your pond.
    I got rid of my algae using a bucket filter with polyester batting.
    had to toss the batting when it clogged, but you gotta trap the algae
    and get it out of the system or it will just dump the nutrients back
    in. that is what the UV filter is doing.
