ProFix complete pond cleaner effectively controls all types of algae, from cloudy green water to string or hair algae and blanketweed in ponds, fountains, bubblers, and streams. Completely safe for koi, goldfish, and pond plants. Controls existing algae and helps prevents algae blooms from reoccurring. Keeps ornamental ponds and water gardens clean & clear.
