Tom I would not buy from them again if they were the last and only way in hell to get any sort of liquid to put in my water table. Don't get me wrong, they make a good product but I went through hell trying to get any from them. I finally found out the name of one of the corporate officers and contacted him. I did get product after contacting him personally but even then they made no effort to correct their problems. I am the sort that once someone get me po-ed enough I refuse to deal with them anymore and they qualified! I did not get enough Plasma Quench to properly fill my table so I went with the homemade recipe in one of the threads on this site. It was MUCH, MUCH less expensive and works just as well. I highly reccomend making your own Tom. I will cut and past in the home made recipe in here and just wish I remembered who to credit for it.
