was brewing up a gallon batch of cs for my buddy, viet nam vet with hep c. my 
rig is 3  6-volt transformers, in series, puttin out 28 +/- volts. cut a lid 
out of 1/2 plywood, and drilled it to accept two 14 ga. silver wires, and the 
fish tank bubbler hose. time got away from me and i didn't stop the brew at my 
preferred 4.0 ma. the batch was about 7.5 ma. i saved that batch for external 
uses, and started another batch. rinsed the gallon jug well, and filled it with 
good arrowhead distilled water, as before. when i dropped the pos and neg wires 
in there, i got a reading of 2.6 ma instead of the usual .40 to . 45 ma. what 
the hey! started another batch, and the same. bad DW??? wasn't gettin the real 
fast turn milkey stuff usually associated with plain tap water. rechecked my 
multi-meter, and it was ok. after a lot of lookin, i noticed that the underside 
of the plywood jar lid was wet. i had been experimenting with the bubble flow 
and aglomeration, and had tuned the air up quite a bit, and the bubbling was 
dampning the wood lid, which apparently was taking the current from the pos 
connecter thru the moist wood to the negative, and was not gettin any current 
flow thru the DW.

this has apparently been happening before as both 14 ga wires were showing some 
etching at the spot they contacted the wood.

any good suggestions for a non-pourous lid????           thanks,     jim
