1. I've heard that the algea "green water" goes away after a period of time, kind of like diatoms. How long is this time? I know that the only way to get rid of algea water is with a UV sterilizer, but I don't have the money for that right now.

2. If the algea stays for a long time, can you recommend any algeacides that would work on a 300 gallon pond? The pond is shaded 40% by floating plants and is in full sun for about 8 hours a day. The pond does not overheat by much because we have had the hottest day in the year and the deepest part of the pond was about 75 degrees.
 
I know there are a lot available, but am clueless to the price. What I do reccomend however is just giving it time..thats a LOT of water to have to treat. Fingers are crossed that it works itself out for you.. Sorry I couldnt be of more help.

Here's an article from another forum.

I might add that my ponds tend to get green water when there are no plants in them however upon introducing the Elodea densa in them, the green water subsides.

Barley straw helps fight undesirable string algae!

1) How does barley straw work to control algae in my pond? When barley straw decomposes in your waterscape it reacts with the water to continuously produce hydrogen peroxide into your pond. This helps to inhibit the development of new algae cells in your pond water.

2) Why should I use barley straw for algae control in my pond? Barley straw is a 100% natural and holistic way to combat undesirable algae in your waterscape. It is non toxic and inexpensive. There is no need to nuke your algae with chemicals because barley straw really works. It has been proven and used for many years throughout Europe.

3) When is the best time to introduce barley straw to my pond? The best time to put the barley straw into your pond is in the springtime between March 15th and April 30th and again in the fall between September 15th and October 30th. The barley straw does not kill algae, but it will help to prevent it from growing. If algae is currently a problem in your pond when you add the barley straw, don't expect miracle to happen over night. It will take several weeks before to see the difference and the algae starts to clear because the barley needs time for decompsition. The best thing for you to do is to follow the routine of adding barley straw to your pond early spring and again in the fall.

4) How much barley straw will I need? A standard rule of thumb is 8 ounces per 1000 gallons. Use an 8 ounce bale for smaller ponds up to about 1000 gallons and a 16 ounce bale for ponds up to about 2000 gallons and so on.

5) Where is the best place to put barley straw in my pond? It works best in ponds that have a recirculating system of some kind, with a waterfall or other type of filtration system. If there is room, place barley straw in your filter box as close to the out flow side as possible, but before the last screen. Do not place on the input side of the box, because sediment will clog up the pores of the Barley Straw and reduce it's usefulness also potentially clogging the filtration system. If you have a waterfall or water inflow point, you can anchor the straw there. If that is not suitable, anchor the straw at the narrowest point at the top of the falls. Your best possibility in an Aquascape Designs ecosystem pond is to put the barley straw into your BioFalls, where the greatest volume of water will come in contact with the straw.

6) How often do I have to replace my barley straw? Your Barley Straw should last about 6 months, but may decline it's effectiveness after 3 months in hot weather when decomposition is occurring more rapidly or algae already exists before the introduction of barley straw to the waterscape.

7) Installation Simply, remove barley straw from plastic bag. Place the barley straw into your pond at the point of greatest water flow, tie cord with some type of anchor in one or both ends if necessary. A rock makes a good anchor. For optimum results have the barley straw floating in the waterscape, but I personally submerge my barley bales in my biological filter box if possible, as explained above. If you place it in the filter box, place uncompressed bag in the box after at least the first set of filter pads to minimize sediment accumulation on barley straw. The barley bale will float for several weeks with no additional flotation device. If and when the barley straw sinks, add a small piece of foam or closed plastic bottle inside the mest bag to help the straw continue to float.

Consider using Barley Straw Extract instead of the bales or the pellets. I find it the most effective and easy to use!

Best of luck and happy pondering!

I recently had this problem and two weeks after getting enough plants to cover 75% of the water surface the water turned clear. It's crystal clear now, even with too many goldfish for the size pond.
 
I use Microbe-Lift, a bottle costs about $25.00 and lasts about a year. It's natural, and safe for fish, frogs, and plants. You simply add a few ounces (depending on the size of your pond) once a month; it takes about a month to start working. But once it does, your water is crystal clear.
 
I've tried the barley straw, numerous chemical/non chemical treatments and every time I've reverted back to a UV filter. I'v just upgraded my UV filter as my old one was too small and not doing enything noticeable. A week later and my water is starting to clear.
