AQUATHOL SUPER K (a granular formulation) DOES NOT reference a livestock water-use restriction (see the linked label: under "environmental precautions").

Only the AQUATHOL K (the liquid formulation) does list a water-use restriction for livestock. Why the two product formulations list different restrictions is puzzling.

The SUPER K granules settle directly within the treatment area. However, the active ingredient is soon released from the granules and may move laterally if currents are present. That is why one should only treat when calm days are expected (preferably two in a row).
