How do I stop the water in my pond from turning green?

During the summer the water in my pond became very murky and green. The pond is 8x6 feet. and I have about 20 goldfish in there. I emptied and refilled the pond but it quickly went green again. Can anyone tell me what to do. I used to have water lillies on the pond but I took them out as they were badly overgrown.

Answers:
algae grows and thrives in water that gets lots of sun. by removing your water lilies you have exposed more of the water surface to the sun and thus encouraging more algae to grow.
Tho this will not harm gold fish, if you have Koi the algae will compete with them for any available oxygen in the water.
You can purchase an algaecide specifically for ponds with fish - will not harm the fish - that is very effective.
BTW: Never empty and refill the pond as - you are removing beneficial bacteria etc that will have to rebuild again in the new water. Good luck and happy ponding

The green is Algae and will always grow in still water. Get a filter or aquatic life that consumes it.

You have to clean it constantly. Consult a pond expert in the store and they can recommend products to keep it clean.
get some type of air pump or fish will help to keep it from turning too.
My wife puts in the purifyer that you use for water beds and it works great. It's just a conditioner and is very cheap. Try it, it works.
YOu'll need a good filter system and if you install a waterfountain to keep the water moving....you'll see less Algae. Good luck..
you got to get the balance right, with three different plants, oxygenators, marginal and the other one I cant remember, but water lily group, also water snails help keep it clean. good luck
i've never used a pump and my water has always been clear
Get a water filter and pump, and put some plant life back as it uses up the nutrients that make the green algae form. You can buy Barley Straw at garden centres that helps as well.
you need a water filter system you'll need to clean the system to
There's a chemical you can buy to dump in there that will kill the algae without hurting your fish. It also turns your water a crystal blue. Try any fish store or home and garden store.
I would also say aquatic life,go to a good garden centre they will advise you
good luck !
You need to get a bubbler or something. The water needs to keep moving.
Use a pump to send the water through a filter. You could incorporate it into a fountain which will put more oxygen in the water. If you use a sand filter, you can scrape the green algae off from time to time and compost it.
During the summer the heat of the day turns the water stagnant and algae begins to grow.

You need to install a small pump to circulate the water I would suggest a solar panel to power this system so it will be free power with only the cost up front

hope this helps also you may want to look into some vegetation to feed off the algae left over
your problem is too much light, no matter what else you do you'll continue to have a problem unless you figure out some way to shade your pond, re-plant your lilies and any other plants you can get, cover 75% of the pond surface, plant shrubs or small trees to shade the pond, build a frame over the pond and cover with shade cloth or build a gazebo over it
anytime you empty and refill pond you cause an algae bloom
do you have any kind of fountain or filter, if not, install one
add some aquarium salt to pond, it will help a little (or you can
use rock salt - icecream salt) - use 1 lb per 200gal
good luck
Algae will always grow, you will have keep it clean, stay on top it.
