Pond Boss Forums AQUATIC VEGETATION Controlling unwanted plants Cutrine Plus & RES

IF you follow label directions the amount of copper in a treatment of Filamentous algae with GRANULAR Cutrine plus will not kill snails. You should not use liquid Cutrine plus to treat an infestation of filamentous algae. The liquid form will distribute throughout the entire water column of the pond and the filamentous algae is not uniformly distributed throughout the entire pond; probably just in the shallowest areas.

Common sense is to just treat the areas infested with the filamentous algae that way less toxic chemical is used to improve the problem. Filamentous algae will always grow when water conditions favor its growth.

If you really want to use a safe herbicide for snails, zooplankton and invertebrates then try the GreenClean brand of granular algae herbicide by - biosafesystems.com
