Item Information

Do not use in ponds or lakes with koi or goldfish. Algae Defense is a broad spectrum algaecide that works fast. Algae Defense works best when water temperatures reach at least 60F Unless steps are taken to reduce the overall nutrients in the pond, multiple applications may be needed for a full season of control. For best results, use with Treatment Booster PLUS.

  • Kills algae fast
  • Do not use in ponds with koi, goldfish or grass carp
  • Works on both floating and submerged algae
  • Fast-acting
  • Treats up to 8,000 sq. ft.
  • Dosage Rate: Mix 32 fl. oz. of Algae Defense with 2.5 gal. of water to treat up to 2,000 sq. ft.
  • 1 gal of Algae Defense treats up to 8,000 sq. ft.
  • For best results, use Algae Defense with Treatment Booster PLUS. Treatment Booster PLUS is designed to maximize weeds/algae treatments by helping to spread and bond the treatment to its target weed/algae. Treatment Booster PLUS also breaks down the surface of the weed/algae allow the treatment to penetrate. When using with Treatment Booster PLUS, mix 32 fl. oz. of Algae Defense, 6 fl. oz. of Treatment Booster PLUS with 2.5 gal. of water to treat up to 2,000 sq. ft.
  • When To Use Algae Defense: Algae Defense should be applied to target algae while it is active and growing. The active ingredients in Algae Defense will be absorbed by the plant killing it entirely.
  • How To Use Algae Defense: Mix the desired amount of Algae Defense and pond water in accordance to label directions. Using a pressurized sprayer, spray the Algae Defense mixture directly onto target algae. Overtime treated algae will begin to brown and die. Once it is completely dead, rake the dead algae away to prevent an accumulation of plant decay and pond muck. We recommend to treat up to half of the pond's surface at any time, waiting 10 to 14 days before treating the second half. In hot weather or when fish are stressed, treat 1/4 to 1/3 of the pond at a time. For deeper water, place the tank sprayer's tip beneath the water's surface.
  • Algae Defense Water Use Restrictions: Algae Defense should be applied when water temperature is at or above 60°F
  • Do not use in ponds with trout, unless carbonate hardness is above 50ppm
  • State Restrictions: AK, CA, CT, DC, HI, ME, NJ, NY, PR, RI, WA or Canada

How much do I need to treat a half acre pond 5-8 feet deep?  Also, My algae is only in the shallower water. (I also use Aqua Shade)  May I pour the mix From the bank rather than spraying? 

Asked by: willingham1
Below are the basic usage instructions for pond Logic Algae Defense. We do not recommend treating any area that does not have algae in it. This is a reactive product so spraying in an area that does not have any algae in it would not be of any benefit to your pond. We DO NOT recommend pouring the product directly into the pond. Spraying as directed is the only method we suggest.

What works on water lilies? I understand that growth happens in shallow water but we have an older pond that is overgrown.

Asked by: Jana H
We recommend using a Glyphosate and a Surfactant to effectively control and kill cattails, water lilies, grass, weeds, poison ivy, and woody brush in open areas of ponds and lakes.
