Brown furry Algae on the bottom of my pond

    We moved in to a new house about a year ago and I have been trying to
    rehab the koi pond after years of neglect.

    So far so good. We have a nice assortment of plants that are thriving
    and after trying out some tester fish I have some Koi that are getting
    bigger. I have a small stringy algae problem but I am taking care of

    I have been using Laguna Phosphate Control, Algaefix and some other
    stuff that adds 'bio-mass' (I can't remember the name but it is a dry
    flake that looks like bran and you mix it with pond water before
    pouring it in)

    The pond only has a pump and no filter. The water is clear but the
    bottom liner and pump is starting to get covered with a brown furry
    algae. The fish don't mind and seem to like to eat it. I don't mind
    as long as it stays at it's current level. Any idea if I can control
    this with chemicals or something. Is this from the bio-mass stuff?

    Sorry to be so vague but I am new to all this pond care. I really
    enjoy having the pond around and the kid love it ( and the frogs and
    the snakes). I don't want to spend the money on a filter right now so
    I hope there is some other way to take care of this. Maybe it is OK
    to leave it but I don't know.

    Thanks for any info,

    In a healthy pond there should be a coating of, as you call it, fuzzy algae
    on things. Sounds to me like you have what would be a normal algae growth on
    the contents of your pond and it would likely be green rather than brown if
    you'd refrain from using the algae fix. .

    It is both unrealistic and unwise to attempt to keep the contents of the
    pond (liner surface etc.) shiny clean and algae free.

    I'm sure the fine people of this group can and will advise you on creating
    and maintaining a balance in your pond that will allow you to minimize
    suspended algae (the kind that makes the water so green you can't see the
    fish) and the beneficial algae that will and should grow on other surfaces.

    Hi AS, :)

    If you keep your fish load VERY low, and your # of plants very HIGH, you
    can manage w/o a filter.

    The way to know if your pond is healthy is with test kits. Ammonia,
    Nitrite, pH, KH and a thermometer. If you have a problem you'll need the
    results of these tests for people to diagnosis what the problem may be.

    How many koi, how many gallons?

    I don't use chemicals, other then Koi Zyme (to keep the bacteria that can
    infect the fish down) and salt when needed to increase slime coat. As far
    as water treatments though, I do use a similar product to your 'bio-mass'
    called BZT once in a great while. Most WQ issues can be controlled with
    small frequent water changes. Are you doing those?
