TetraPond UV water clarifiers will permanently remove green water, by destroying it and allowing the filter to sieve it out.

Green water is caused by the presence of millions of suspended algae cells, which multiply rapidly during the spring and summer.

Not only is green water unsightly, but it can also adversely affect the water quality in the pond.

TetraPond UV's come with a 2 year guarantee.
