Does anyone have any recommendations on how to keep my pond water clear it has a pump bigger than it should have and won't stay clear its a greeny colour most likely algae. I have bought some chemicals, but is there any other way like barley or something to help keep it clear? Oh and the pond is about 200g-250g which will have 5 comet goldfish in it tommorow.
TIA

Hi Angel. I know exactly what your going through. We had a pond that we couldn't get clear for about 10 years. We tried everything. A friend of ours suggested we try making our own biological filter and in ten days our pond was crystal clear. You can find a copy of this diagram at our clubs website in the water conditioning section at: www.geocities.com/ont_pondkeper
The reason why the water is green is because there is too much nutrient in the pond that is feeding the algae. The size of the pump has nothing to do with keeping your pond clear, it's the biological filtration which builds colonies of good bacteria which removes ammonia and nitrite from the water which keeps it crystal clear.

The plant "anacharis" is great for consuming nutrients in the water, thus keeping the water clear. Hornwort is apparantly also good for repelling algae. These are popular pond plants. :)
 
giving the surface about a 60% covering with water hyancith and water lilies should help, using this and the other suggestions I doubt you will have ANY green water, and your fish won't become easy snacks for the local wildlife.

Well, for my pond, which has a similar problem and we have a pump and filter system that is also larger than it should be for it, we got floating plants to help keep the algae down, a UVC light also helps, and you can also try a few freshwater clams. They've helped keep mine quite clear.
 
I have a similar situation as Angel Freak. I have about 200 gallons with starter goldfish and the water seems murky. I also purchased, about a month ago, some water plants (I believe water hyancith) for shade and for other advantages for having plant life. I am seeing these start to 'multiply' like I suspected they would.

A few days ago I threw a power flo filter inline with the pump (the previous owner had no filter). When can I expect (if any) for the water to clear up? I guess it is a little deceiving given that the liner is black. I am constantly watching the ammonia/ph levels and everything has been going well. I also replaced about 20% of the water about a week ago.

To make the water more visible I was considering either lights underneath or purchasing the bioligical filter 'add-on' for this filter - making it essisentally a powerflo max. Any thoughts on either of thse techniques? How do the fish generally react to underwater lights?

Thank you for any insight.

Edit: Thanks! s/Furky/Murky

As far as furky water well i dont know :D
Murky water can be fixed with this stuff if you want Pond Clear

or do what Barkarole said, you can get filters with built in UVC treatment which does help to keep it clear

Keep your pond Clear

If you have a biological filtration system large enough for the size of your pond, you will never have hair/blanket or suspended algae. Many places make filtration systems that say they will be specific quantities of water but they never seem to add the amount of fish that will be inhabiting the pond. So, if your pond water is so green you can't see your fish or the hair/blanket algae is so long your fish are getting trapped in it, just another biological filter. Check out our clubs website at: www.geocities.com/ont_pondkeper where you will find a diagram on how to make your own. It's so very easy.

You can also try some bales of barley. They work great for controlling algea and are inexspensive. Most pond supply stores have them.
