My backyard pond is failry new (this spring) and the water is always
green. I've tried the chemicals, cleaned the filter and added lillies
and other vegetation to block out the sun. Nothing works! The water is
green as ever, any suggestions?

Aerate until nutrients are used up. Algal growth will stop. This may
take a while though, depending on size of pond size of pump (air or
water). Don't suppose the pond has a fountain?

I had the same problem with a small pond (100 gal) that I have in the
front garden. It's in full sun and stayed green no matter what I did.
I finally consulted a pond expert. We pitched the underwater filter
and went with an external one with UV sterilization. (I went with a
Laguna Pressure-Flo - and sized it about twice the rated size since I
intend to add a water fall soon. I _love_ this filter, by the way!)
After a couple of weeks with the new filter - the pond was crystal
clear. I can actually see my goldfish now!

ponds without fish will eventually clear after the nutrients in the
water are used up. adding new water will send the pond back to green.
aeration is absolutely essential to clearing ponds.

the quickest way to clear a pond is with UV, but the mangled and
clumped algae must be removed from the filter to remove the nutrients.
the long term solution is a veggie filter to clean the water with or
without fish. without fish the veggies can be in the pond, with fish
the veggies need to be somewhere the fish cannot chew on their roots.

What chemicals have you tried?

I have heard that big ponds do not have that problem, small ones do.
I do not have a pond, however almost all of my neighbors do.
Many of the smaller ponds have windmill pumps to aerate the water. They
also add blue die to the water to make the water darker. The darker the
water, the less the algae growth.

Next door stocked his pond with pickerel and other fish, but he does not
eat them. It is cool to watch the kingfisher birds dive in to get their
meals. His is a large man made pond about 20 feet deep and 150 feet wide.

Their are several businesses in my area that specialize in ponds.
Like the previous poster check out a pond expert. If you live in
Southeast Michigan I can email you the names of such businesses.

Enjoy Life ..... Dan

Green is a healthy sign. You probably have algae bloom due to high
nitrogen. Wheat hay or fish can help, but really no need to be
concerned.

Oops, that would be barley, not wheat. Also some plants such as
anacharis will reduce algae, but that one can be invasive.

Barley straw is said to help.
Fish just add more nutrients and increase the green load. fish dont
eat the pea soup type algae, actually, koi and goldfish arent
herbivores in general. Ingrid

You need some floating plants that you can remove as they multiply,
water lettuce, water hyacinth, duckweed , etc. Just try to pick one
that isn't an invasive in your area. Let them use the nutrients and
then remove them to your compost .

Sound advice!

We just added water lettuce and water hyacinth. Plants a crucial item
.. Filters those things we can't see. Just replaced my filter which is
physical, charcoal and maybe bacterial an hour ago.

I'm in agreement with all the others suggesting more plants. A couple
other suggestions:
Minimize feeding of your fish. The most common cause of pea soup water
is excess nutrients, caused by either / or too many fish, or overfeeding
of fish. Most fish food is quite high in phosphates. Excess phosphates,
along with nitrogen, and algae flourishes.
If you already have a good number of plants, and still have lots of
algae, another good thing to try is adding Potash to the pond. Buy a
small bag of Muriate of Potash from you local garden center. It's very
cheap. I add a small handfull to my roughly 1500 gallon pond every
couple of weeks during the summer months. Very unscientific dosing
method I use is, when the Red Stem Parrots Feather & Water Celery, or
Hyacinths & Water Lettuce seem to be slowing in growth, or are not that
nice deep dark green, time to add more potash.
Higher plants typically need all 3 of the major nutrients to thrive.
N,P,& K on a fertilizer bag. Algae, however, will thrive on only one or
two macro-nutrients. A shortage of K, which is seldom high in a pond,
will allow algae to take over. With a more balanced nutrient mix, the
higher plants can out-compete with the algae for available N & P, and
the result is clear water.
I also periodically add a bit of Liquid Iron/Trace Element to the pond.
You can buy high priced (& very diluted) trace mix from a pond or fish
store, which comes with specific dosage instruction. I'd prefer my money
to be in my own pocket, so I buy the quarts of Iron/trace concentrate
from the garden center, and add a teaspoon or so at the same time I add
potash.

Add vegetation and more vegetation...had a customer give me a bunch of
vegetation..parrots feather and a "grass" looking plant. In less than
two weeks the water went from a "pea soup" to clear water.
