Algae Control
Unsightly algae blooms can hinder the natural beauty of your pond, and can become uncontrollable if left untreated. All ponds begin accumulating organic matter from the time they are first filled with water, generated by waste such as algae, dead plants, fish food and fish waste, and garden debris that may enter your pond, but API® pond products make it easy to control algae and other pond waste, so you can maintain clean and clear water to reduce maintenance over time. Spend more time enjoying your pond and less time troubleshooting!
Powerful and fast-acting POND ALGAEFIX™ algae control has been used successfully by pond owners for over 15 years to effectively control green water algae, string or hair algae, and blanketweed without harming fish or plants. Weekly use of POND ALGAEFIX algae control will reduce pond maintenance, and contribute to a clean, clear pond environment.
For those who prefer an alternative approach to algae control, MICROBIAL ALGAE CLEAN™ algae control contains patented, live bacteria to control green water and reduce organic sludge to promote a cleaner pond environment. It is the first bacterial algaecide to gain EPA registration, and may be used in ponds, fountains, and waterfalls with live plants and fish.
