Refilling the dip tank

26.7.6 Refilling the dip tank Since acaricides are less effective in dirty water, dips should be periodically drained (or pumped out) and refilled when the dip solution becomes “dirty.” How frequently the dip solution is changed depends on the size of the tank, soil type, rainfall and the measures taken to keep the dip solution clean. Areas with clay soil and/or heavy rainfall will spoil the dip much more rapidly than sandy soil and/or dry climates.

Here is a general guide:

 Dips with a volume of 9,000 up to 13,000 liters should be drained and refilled with fresh solution after 20,000 to 25,000 head of cattle.

 Dips with a volume of 13,000 up to 18,000 liters should be drained and refilled with fresh solution after 30,000 to 35,000 head of cattle.
