WHEN TO APPLY
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 APPLY
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 the target algae. Use with Treatment Booster Plus for best results. Over time, treated algae will begin to brown and die. Once it is completely dead, rake the dead algae away to prevent plant decay and pond muck accumulation.
WATER USE RESTRICTIONS
Algae Defense is not recommended to be used in ponds with koi, goldfish, grass carp, or trout, unless carbonate hardness is above 50ppm.
STATE RESTRICTIONS
Algae Defense can not be shipped to Alaska, California, Connecticut, District of Columbia, Hawaii, Maine, New Jersey, New York, Puerto Rico, Rhode Island, Vermont, Washington or Canada.
