Hi rondellejones,
In response to your question about plastics, my two bottles are PET. See the pics of my 'quickie' set up (
genesis2forum.org/index.php?option=com_kunena&func=view&catid=16&id=8260&limit=6&limitstart=6&Itemid=66#8282). Right after generating, the smaller bottle that had the MMS and HCl activator is yellow, but after exposure to the air for a few days it goes back to clear. I do not see any pitting in it at all, nor in the other clear PET bottle for receiving the gas.
The tubing I am using looks to me like it is HDPE it is a translucent whitish (just like 'natural' hdpe), and is quite stiff. I have not noticed any pitting with it. It is yellow right after generation but then after a few days in the air it clears up again. I think it is food grade because it is the same tubing they sell for installing icemakers. At home depot (lowes too I am sure) it comes in a 25' roll and is pretty cheap. The label says "Watts" is the maker: "polyethylene tubing 1/4" x .170" x 25 ft."
I have generated twice now, 800 ml and 1000 ml and have not noticed any pitting of the plastic, and in fact the plastic looks good.
I do want to work on a glass setup. If someone finds sourcing for this, please post some links.
Thanks,
Michael
