Here's the recipe for home-made PlasmaQuench

NOTE: nitrite NOT nitrate!
1 teaspoon of Physan 20 ($8/8oz bottle) "antibacterial/antifungal additive"
1 oz Ultramarine blue food-grade dye ($5/oz.) "color added so folks won't drink out of it!"
Mix well, treats 75 gallons of water.
All prices include tax and/or shipping.
I made my own water table and anyone with a little metal working experience should be able to do it. You can follow the build of my table at http://www.cnczone.com/forums/showthread.php?t=63124
If I can do it, anyone can.
