Question

Does anyone have any "natural" remedies for removing algae from a fish pond?

Answer 1

Put in snails or algae-eating fish.

Answer 2

For the algae on the sides, buy a fish called a hypostemus plecostemus. It is the most efficient algae eater. I buy mine every year when the ond reaches 70 degrees, and when the weather cools I sell it back to the fish store at the same price I paid, because by then it is three times the size!

For string algae, put a natural barley bale in the water and leave it for two to three months. These are available at pond stores.

The BEST method for keeing your pond crystal clear is using a UV light. Tetrapond makes a good one and there are lots of other brands, too. The water runs through the light and the UV rays kill the algae spores.

Answer 3

Try lots of floating plants. They will shade the pond and algae can't grow without the sunlight. Also they will extract nutrients from the water which help  the excess algae grow. They make a floculating agent (available at pet stores) that you can spray onto the pond. This will cause suspended algae to clump together and sink to the bottom. You then siphon it out or remove with a fine mesh net.
