First of all, Miracle-Mineral-Supplement is a 28% (by weight) solution of sodium chlorite. There are some dangers associated with handling this concentration, so I have been recommending that people dilute this down to a 5% concentration.
The 28% solution is made from 80% technical grade sodium chlorite powder, so the actual yield of sodium chlorite is 22.4%. To get to 5% you would put 1 part 22.4% in a glass and add 3.48 parts water. This will give you 4.48 parts with a concentration of 5% that is much safer to handle.
The best way to use this with pets is to put 0.5 ml of the 5% sodium chlorite solution in 1 gallon of water and give that as drinking water. This will eliminate slimy biofilm from forming in the water dish, and the sodium chlorite will become activated by the acids in the pets stomach.
