I have used stainless pot lids for my anodes for 15 years with no problems.  I
have changed the liquid in the 5 gallon bucket perhaps every 3-4 years, after
adding a bit of water and more washing soda in the interim - I wait til there is
a layer of crud on the bottom.  I have poured on the lawn with no visible
effects.  The biggest problem I seem to have is keeping the alligator clip that
is submerged intact - the wire wants to corrode at the clip and I need to
refasten it periodically.

knowledgeable galoots give me some comfort or warning here? The amounts don’t
concern me for ground water, etc., and no animal is stupid enough to drink this
slurry . . . mostly I want to make sure I’m not poisoning trees in the immediate
area.
