The BiospherePRO biodegradable sphere will treat ponds up to 1/4 acre in size (of moderate to shallow depth) or up to 250,000 gallons of water volume.

The 1/4 acre BioSphere Pro will treat ponds up to 250,000 gallons or can be combined to treat larger ponds. Safe and useful for a variety of conditions, the spheres will help reduce organic nutrients, muck, and sludge which can lead to many types of unwanted growth.

Please do not under-dose for the best results.

Each sphere will treat your pond for a full 30 days and will degrade naturally, or you can remove it and place it in your compost bin. Will work for all-season pond care in temperature ranges of 34 degrees to 100+ degrees.

Save when ordering 3 or more!

Tips for the best results with this product:

• Dose appropriately for the gallon volume of the pond and the estimated
  nutrient load. The product has a high safety threshold so using 2x or
  3x the pond volume is still safe for fish.
• All microbial products will work best with a good pond aerator in place.
• If the current water chemistry is unknown, a pH test is advised. This product will work best in a range from about 6.5 to 9.0
• Do not open or tamper with the sphere.  Microbes are released automatically upon submersion in water.  The spheres are designed to sink.
• Do not use any microbial with copper-containing algaecides.
• Allow a reasonable time for the microbes to work. 30 days minimum and
  ideally up to 60 days (or two treatment cycles) for the best evaluation.

This all-natural product does not kill algae or weeds. The EPA requires that we use careful language when defining the effects of this kind of product vs algaecides/chemicals. If you have any additional questions on how to use this product, please
