A patented timed-release system incubates and releases beneficial bacteria and enzymes 24 hours a day, 7-day a week, over a 30-day period.
Each sphere treats up to 1,000-gallon (to calculate pond volume in-gallon, multiply pond length x width x average depth x 7.5). Being all-natural, you can't overtreat. PRO formula works effectively in water from 34° to 110°F.
Ideal for stock tanks, koi ponds and small ponds. Safe for humans, pets, fish and plants. Made from a corn-based polymer; after 30-day, sphere can be disposed of or composted.
Replace every 30-day. May require 4-6 weeks to achieve water quality improvement. Most effective in ponds with pH level between 6.0 and 8.5.
Includes string for easy retrieval. Disclaimer: Molded from resins that have been certified compostable to the requirements of ASTM D6400 and shown to be marine degradable per the requirements of ASTM D7081. Made in USA.
