Best Way To Control And Eliminate Algae.
The halo ultraviolet light that I purchased for my 165 gallon pond was a good investment at an excellent price with free shipping. After installing the light, it took about 6 days when my pond's clarity improved dramatically. The pond water is now clear and my fish are highly visible even when they are resting at the bottom. I am very, very happy with the halo ultraviolet light.
Not only is the water crystal clear but my filter was very clean when I checked to see if it needed cleaning. I highly recommend this light to anyone having a problem with cloudy water or problems with algae.
