Hi, can anyone tell me how much caustic soda to put in my cesspool? And
when do I add it, on a monthly basis or just when it starts to fill up
and needs to be pumped?

My Dad recently died and with him died the directions on how much and
how often he added the caustic soda. All I know is that he always wore
gloves and a mask when working with the caustic soda. Any info would be
appreciated. Pam
