CDS (Chlorine Dioxide Solution) with Jim Humble - 1st video

Hi to all and thanks to Michael, Rainbow and Pam....

Thanks for the info....

Pam, I'm interested in measuring the concentration with test strips...could you elaborate or point me to some reference? Only thing I've seen so far are 3 videos, Jim's, Andreas' and one other.

Got a problem....my rubber bottle stopper is melting rapidly. I can't bring myself to use baby bottle nipples....any suggestions?

I'm making a batch of 32oz daily, using a little bit for myself, and the rest is going on my aloe plants which have been fighting a losing battle against fungus for over a year. The weather is cool here in Fort Lauderdale now, so I don't expect fast results, but I will let you know when I see some action. I'll show you a 'before' photo so you will know what I'm up against. (don't know if the photo got uploaded or not)

Hi, Clam - here's a link for silicone stoppers that was posted earlier on the forums (and thanks to Nir who posted it) -

Michael posted directions for using the test strips - I'll have to go get that particular post and link it here.

(surprisingly enough, it was in this very thread!!!! )

Boy, I'd love to hear about your plant fungus - I'm thinking about treating my fruit trees...

Hello Michael, Did you find the meter and CD reagents more accurate, simpler, quicker what ever to use?

Still waiting to receive the reagents. Will let you know. If you order them, order them both at the same time. The reagents take a while to get. One person put a bid on the meter for $85 and the vendor accepted it.

To all members who make their own CDS.

I have just received 0-500 ppm chlorine doxide testing strips and tested CDS that I prepared using the exect technique shown by Jim in his long video (with the exception that my water was ice cold as in the first short video). The process was picture perfect. However, the testing iis difficult because of high CDS concentration. It is difficult to judge the number of ppm from the color of the indicator. So, I diluted the CDS at 1 to 40. It is 1 ml of CDS and 39 ml of distilled water. At this dilution ratio, the testing strip showed concentration of about 150 ppm. Therefore, the original CDS concentration is 150x40=6000ppm which is close to what Jim determined and showed in his video. It is probably better to dilute the original CDS even more to increase the accuracy of testing.

I filled two plastic bottles (from the original MMS, 4oz each) and will be using one bottle for maintenance dose
(1ml of CDS=6 drops of MMS) once a day. The second bottle is in the freezer and I will check it after the first bottle is finished. I will let you know if freezing preserves CDS for a long period of time.

Hey Michael, I put in an offer for the CDS tester but have not heard back as yet. But I see they say they come with reagents? As below.

Each eXact Chlorine Meter comes with a Mixing Cap, Cleaning Brush, Instructions and two 100 test bottles of reagents (DPD1, DPD3) for the Chlorine Dioxide tests.

Woofy, you need to be testing for chlorine dioxide, not chlorine.

Hi Pam,

it's Alex here and this is my first post. I am sorry to bother but you seem to be the right person to ask to. I am a bit cofused. I am planning to make some CDS following the latest Jim Humble's video. There is one thing I don't understand though.
I know that in the reacting bottle I have to add 1oz of MMS to 1oz of citric acid. What confuses me is that Jim and everyone else in the forum talk about a 50% citric acid solution. How do I make a 50% citric acid solution??? I have just received my supply of 1 bottle of MMS and 5 bottles of 10% citric acid solution...that's not the right one, is it?

How can I make a 50% citric acid solution???
Could you please give me a simple and practical example to follow to be able to proceed with my experiment?
I would very much appreciate your help.

Thank you very much for your very helpful advice on this forum.

Hi, I'm a newbie too, but I have been having great success just mixing one teaspoon of powdered citric acid and one teaspoon of sodium chlorite flakes in four ounces of water, to make 32 oz of bright yellow CDS.

Hi, Alex. There are lots of people here who have really good experience making MMS and citric acid .

Everything is done by weight, BUT, water and citric acid are so close in weight, you can simply take an amount of distilled or reversed osmosis water (say 1/3 cup) and add to it the same amount of citric acid (packed) - (a packed 1/3 cup, if you've used 1/3 cup water) and mix. It may take a while for the acid to dissolve (I put mine in a pyrex cooking container and heat on the stove for a bit, low heat, to help it dissolve - otherwise, you can just put it somewhere out of the way and leave it for a while, and it will dissolve) -

I use only glass, plastic and wood when making citric acid and MMS. I'm not so sure it's as big a deal with citric acid, but I just want to stay in the habit of using one set of "utensils" for my MMS production. MMS will oxidize metal, so you definitely want it away from your metals. Also, if you have natural stone counters, I'd be sure to wipe up any spilled citric acid. I have a nice set of concentric rings in mine, and that tile will have to be replaced, eventually. Just didn't think -
