Answer 1

EDITED:PLEASE READ
what you have described is pea soup algae PLEASE for they health of your KOI read the links below this type of algae cuts off the oxygen supply.
OXYGEN is a key element with koi unless you have a good filtration system and aerator you can't use only the barley (which is excellent) you must circulate . **** YES ****A UV filter
will positively REMOVE (split pea) this type of algae. HOW DO I KNOW THIS? I lost 3 fish in one day and immediately knew what happened. I WAS lazy and didn't change the lights in the filter soon enough. I would have lost all of them but I began pumping fresh water in and pumping out the old at the same time.
I then took out the rest of the fish and completely emptied the pond replacing the lights in the filter and adding fresh water.
The UV light does not add chemicals.

So Koi need a lot of oxygen, almost as much as we do when resting.

******************************************

Depending on the pond size selecting a UV light will remove the green.
I use 24 watts in my pond but it is small only 2000 gallons at present time. Also using an aerator will prevent it. Algae doesn't like lots of oxygen but koi REQUIRE a lot .
The aerator will help provide what your fish are in short supply of right now. This is my hobby so I've researched everything possible.
Here are some suggestions and links for research on what you need and costs.

Use oxygenator plants as well to create a natural filter system as well.
Good Luck!

Answer 2

If it is a new pond and you have just changed the water, or keep changing it to clear it up, stop doing that. The normal process with a new pond is what it called an algae bloom that clears up in 6-8 weeks, if you leave it alone. it is helpful if you can have 60% of the water surface coveredwith plants but I know that isn't practical with Koi that are vegetation eaters. Don't add chemicals to clear it up, they are bad for other plants and fish. You do need a good filter on your pump if you don't have one. Barley will help clear up the algae problem also, you can get bundles of it at your garden center. It takes a little time to clear it up, but it does work, even on filamentous algae which is notoriously hard to get rid of. You just toss it in, it will float for a while and then sink to the bottom so you don't see it.

You can get a pool paint for your cement pool, it is a two-part epoxy. You have to let it cure thoroughly before you put your fish back in. We used it on concrete fish tanks at the nursery where I worked. Be sure you get one that is non-toxic. I believe they use it to paint the insides of stock tanks, so you might be able to get it at a farm supply store.

The fish don't care if the water is green; it is the humans that don't like it.

Answer 3

whether that's a sparkling pond and you have in basic terms replaced the water, or save changing it to sparkling it up, end doing that. the conventional technique with a sparkling pond is what it called an algae bloom that clears up in 6-8 weeks, in case you go away it on my own. that's effective in case you may have 60% of the water floor coveredwith flowers yet i understand that's not useful with Koi that are flowers eaters. do not upload chemical compounds to sparkling it up, they're undesirable for different flowers and fish. You do want a reliable filter out on your pump in case you do not have one. Barley will help sparkling up the algae difficulty additionally, you will get bundles of it at your backyard midsection. It takes a touch time to sparkling it up, in spite of the undeniable fact that it does paintings, even on filamentous algae that's notoriously complicated to eliminate. you in basic terms toss it in, it is going to waft for a on a similar time as and then sink to the backside so which you do not see it. you will get a pool paint on your cement pool, that's a 2-area epoxy. you're able to enable it treatment thoroughly in the previous you place your fish returned in. We used it on concrete fish tanks on the nursery the place I worked. be sure which you do get one that is non-poisonous. i've got faith they use it to paint the insides of inventory tanks, which you're able to be waiting to get it at a farm furnish keep. The fish do not care if the water is eco-friendly; it somewhat is the people that don't like it.

Answer 4

I have 2 water gardens with gold fish. I, too, have an algae problem, but it's caused by sun and heat. I won't have koi so I can enjoy plants. I have about 70% of the surface shaded with duck weed, lily pads, and hyacinths. Nothing will prevent the algae. I have heard that tinting the water blue helps.

Answer 5

1. you need to shade the pond, to much light = heavy algae.

2 improved filtration,

3 do not paint till you talk to an expert..

4 remove pond lighting.

Answer 6

I've been using barley straw for five years on my two ponds with great results. As a result of my success the county is going to try it this spring on a 27 acre lake. Here's a good link http://www.btny.purdue.edu/pubs/APM/APM-1-W.pdf RScott
