SeClear is the first aquatic algaecide and water quality enhancer in one designed to replace routine algaecide treatments. Delivering longer-lasting results, improved water quality and reduced maintenance through time, SeClear provides effective control of a broad-range of algae species while reducing in-water phosphorous levels with each application.


Control the Problem — and its Source


Applied at the first sign of an algal bloom, SeClear's copper ions inhibit photosynthesis in algal cells, providing fast-acting control, while simultaneously removing phosphorus from the water column. SeClear gets to the source of unsightly algal blooms, reducing the amount of nutrients available and lowering the chance of a recurring bloom.


Control will occur in 3 to 7 days following application and water bodies should be retreated when regrowth appears. Water treated with SeClear is completely safe on turfgrass and ornamental plants and can be used for irrigation immediately.


Uncontrolled Nuisance Algae Can Cause Big Problems

When left unmanaged, nuisance algae can cause the loss of oxygen, death of fish, and hinder water’s use for swimming, fishing, drinking, power generation, and irrigation. Excess levels of phosphorous (e.g. eutrophication) is a widespread problem in rivers, ponds, lakes and reservoirs.


Because of eutrophication, successful management of 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 does nothing to address phosphorus and water quality.


Benefits Include:

  • Treats the algae present
  • Reduces the amount of available phosphorous and suspended solids with each application
  • Provides algae control
  • Allows for longer intervals between applications
  • Reduces the field for follow-up applications
  • Enhances water quality
