Want to achieve a beautiful clear pond? GreenClean PRO and GreenClean Granular Algaecide are environmentally friendly companion pond products. For those with large sized water features or ponds GreenClean PRO will attack planktonic algae on contact, killing algae within hours of application. For those with smaller water features, ponds and waterfalls, GreenClean Granular Algaecide is the perfect complement, providing organic production and algae control. These two granular algaecides can also be used on hard surfaces like walkways or pavers, while our liquid algaecide is the perfect alternative for those with a recirculating system.
