how to get koi pond water cleared up?

Question

we have done several water changes, and added algae clear.

Answer 1

Barley straw when put in a pond will clear it of algae for some reason. Many pond supply stores sell mats and/or balls fo the stuff that you simply drop into your pond.

Answer 2

You did not say how many gallons of water or if it is outside. There are two kinds of algea. 1 long stringy stuff but water is clear or 2 green partical algea suspended in water making water so that you cannot see through it. The string algea(1) is easy. No More Water Changes or chemicals. The string algea feeds from nutrients in water. Everytime that you add more water you replenish the food supply. Let the algea eat all the nutrients in water and it will die by itself. Bottom line just leave it alone. The next (2) there is a simple solution and that is water hyacyths.sorry do not know how to spell. My pond is 12 foot across and 4 deep and by putting in 10 plants the pond was crystal clear in 2 weeks. Remember that koi will eat the roots so if you can't seem to get them to live try water lettuce. Does the same job but koi usually do not eat the roots. Ps The other thing that we dod was put a 13x13 canopy over pond. Algea need sunlight to grow and ours keeps the sun down, water temp down, evaporation down and has been the best thing that we have done. Remember less is better so just throw some floating plants in and leave it alone for a month. The more you do the worse it gets. Trust me I know lol

Answer 3

it depends on if its green or just milky. If its milky thats normal, all tanks including ponds go through this when they are new. It can take up to 2 months to clear up. Since you have done water changes. I would figure 2 months from the last water change. Just leave it alone and it will clear by itself.
However there is another reason for it to be milky, over feeding. If you have fish in there, only feed them once a day and make sure its just enought that it is gone in at most 10 sec. Fish have a 3 secound memory and will forget that they just ate, and will eat more, which will go right through them causing a drastic spike in the amonia level, which can cause cloudyness. If you suspect this do another water change and reduce feed. Also take a sample of your water before and after the water change. Most petstores will test your water for free. This way you can see if it is the amonia. The amonia should read 0.
If its green, its algea. There are two ways to clear this, Liquid which you have done (try a different brand). and theres a uv sterilizer. These can be seperate or attatch to your pump. They help clean the water, reducing algea growth and diseases.

Answer 4

you must reduce the amount of light to clear your water
add more plants, try to cover 75% of your pond surface
plant small trees or bushes around pond, build a
gazebo over your pond, just anything you can do to
reduce the light
i know all the books tell you to build the pond where it
will get sunlight but that is mainly for the plants to bloom
the best thing you can do is build your pond in shade
