  • Rehabilitates Aquatic Environments - By using environmentally-safe methods to remove invasive algae, Lake Guard Blue restores the natural habitat to its pre-bloom condition.
  • Proactive or Reactive - Can be used both proactively—to prevent algal blooms from forming— or reactively—to remove existing blooms.
  • Works on Waterbodies of any size - Lake Guard Blue product contains 10lb of active ingredient, sufficient to rehabilitate approximately 1-20 acres of water. Approved for use in fresh, brackish and salt waters. Not intended for small personal ponds, fish tanks, pools or Koi (or other ornamental fish) fountains.
