Because of eutrophication (water body aging) successfully managing nuisance algae and improving water quality can be difficult. Other copper-based algaecides—such as the old standard, copper sulfate—can control some algae present but do nothing to address phosphorus and water quality. Thus, management can turn into a cycle of application, temporary improvement and rapid regrowth, with no progress toward long-term water quality improvement.

Our SeClear formula solved that problem by:

  • Treating the algae present
  • Reducing the amount of available phosphorous and suspended solids with each application
  • Providing algae control
  • Allowing for longer intervals between applications
  • Reducing the field for follow-up applications
  • Enhancing water quality


With the development of SeClear G, SePRO has again advanced the science of algae management. This new granule formulation provides all of the proven algaecidal and water quality enhancement benefits of the liquid SeClear formulation with several improvements.

  • Controls surface and bottom algae (including Chara)
  • Broadcast as a granule or dissolve and spray
  • Typical application rate: 15 to 25 lbs/acre
  • Improved economics
  • Available in 20 pound bags
