I don't see where the single bottle method turned into the 840ml bottle for dosing.
The 840ml bottle of CDH made using the Two Bottle Method is used as an example here. You can make CDH using the 12 hour One Bottle Method or 10 minute Two Bottle Method. Both will give you about the same amount of CLO2 per ml of solution.
Since you are dosing a dog, you would give less than a human would ingest because of the difference in body weight. Comparing dosing between MMS and CDH is not so simple as MMS may continue to activate inside the body whereas CDH doesn't have as much unreacted SC remaining. But, Scott and I think 1ml of CDH will provide about the same amount of CLO2 as 1 drop of MMS if the MMS continues to activate inside the body.
So, I suggest to start with 1/4ml, which is 6 drops of CDH for your dog. (24 drops=1ml) If using an 8 fl oz dosing bottle, then add 8 times 1/4ml which would be 2ml added to the bottle. Then take out 1 fl oz per hour which will contain 1/4ml of CDH.
Dosing in mg of CLO2 is the best way when you know the amount of CLO2 in your stock bottle of CDH. If made according to the recipes and in similar bottles, you should have about 840mg of CLO2 in the 240ml of solution. That is easy to determine if you know the CLO2 concentration of the CDH solution. On average, when made according to the recipes, the CLO2 concentration will be about 3500ppm. If you made 240ml of CDH, for example, you would multiply 3500 by 0.240 and get 840mg of CLO2. See the formula in my signature line below.
840mg divided by 240ml equals 3.5mg per ml of CDH. So, 1/4ml of CDH will contain 0.9mg of CLO2, almost 1mg.
Having test strips is informative, but if CDH is made according to the recipes and using the same equipment, you may not need the strips. And dosing can be determined experimentally. If too much, a Herxheimer effect will be noted. Always start low and slowly increase dosage.
The test to determine what happens when activating CDH in closed or open topped bottles was an experiment for information. Some are interested in the results. It has nothing to do with following the current recipes for making CDH.
CDS is a different solution compared to MMS or CDH. It contains only CLO2 in distilled water, and can also be made overnight or in a short time like CDH, but it is quite different than CDH. It will not continue to activate inside the body because it does not have any unreacted SC in it.
MMS and CDH both contain CLO2 and some unreacted SC and may continue to activate inside the body. MMS has much more unreacted SC than CDH. The main difference between MMS and CDH is the activation time. Doesn't seem like a big deal, but it can be!
