Does What is says on the tin!
Ok my husband fitted it fairly easily and our pond is crystal clear, changing the filter is so much easier than our old one.
The only drawback is the inspection chamber for the UV light, it is extremely difficult to see if he light is operating.
After we called in an electrician who fitted up another switch which lights up when all is operating correctly we are now satisfied with the product.
