Caution: Do not use Pond Care AlgaeFix with crustaceans, including; crabs, shrimp, freshwater shrimp, and freshwater lobsters.


WARM WEATHER CAUTION: Before using Pond Care AlgaeFix make certain that the pond has vigorous aeration - e.g. a fountain, waterfall, or aeration device to avoid fish loss due to low oxygen levels. When algae is removed by the filter or settles to the bottom of the pond, the oxygen level may drop to a harmful level if adequate aeration is not provided. Therefore, when using Pond Care AlgaeFix during warm summer months, adequate aeration is required.


Do not shut pond pumps and aeration devices off at night.
