Making CDS using an aquarium bubbler

Hello, I'm brand new to the forum, but not new to MMS and CDS. I used to make CDS with a small glass within a glass. That was great, but now I want it done quicker and more concentrated. I'm now using an aquarium air pump, with a stone bubbler, (so as to make smaller bubbles therefore making it more efficient.) Or so I thought. The MMS container is airtight...But, I found that while using this setup, for an hour-or two, the CDS dissipated faster (from the water) than it was collecting it. When I came back to see how it was doing, The CDS water color was a lot lighter than it was before. How can that be? I had even covered the CDS bottle with a wax paper plug. Was the CDS being absorbed by the stone bubbler, or were the bubbles helping to dissipate the CDS, as the MMS was finishing up it's magic? The MMS still had a smell, was still slightly colored. Was I doing it too long? Has anyone else come across this problem?

I use a stone bubbler and aquarium air pump to make CDS.

the stone i use is for OZONE generator (the MMS gas does not react with it ) and with the air pump i use a small faucet to make the air and the MMS gas go very slowly through the air stone (i bought it at an aquarium store). i put MMS mix in hot water ( 80-90 Celsius).

That way i make 200ml CDS 6000 ppm in about 10 minutes.

Hope that helps...

I think it will only outgas/form gas at a certain rate, and perhaps you were just adding air!

As I recall, Jim blew for a bit then had to wait for it to react and the gas to build up before giving another puff of air or so.

You may have to heat the mixture to get it to react faster...but I'll defer to another more informed than I.

Hi Healthy and welcome to the forum . OI am not te expert here but I can lead you in the right direction. GO to the main INDEX page.. then scroll down till you see MMS Technical Talk then click that and at the very very top it will say CDS and making it or something like that click that and there you will find all ways to make it. I do the glass jar with the floating shot glass.. so easy to make but if you need further assistance Pam..Bruce or Steve or Michael can help you..they arre the moderators here.. again welcome to the forum and good luck in your journey

Nir,

I believe the reason Jim stopped using the stone diffuser for CDS was because he found that, in time, the gas of the CDS was starting to breakdown the structure of the stone cause of the heat generated by the CDS.

I was amazed by this because I use an ozone machine as well, and have glass stones (no resin holding it together) and the glass stones have been melted together by heat... so it is a pure bond. And Still, the CDS gas was able to break it down. Pam, Michael, please correct me if I'm wrong here.... cause I REALLY wanted to use the stones too, cause it was a lot more efficient with the tinier bubbles distributing the CDS gas into the water.

Would love to know other peoples experiences using the stone diffusers..

I think a number of people had problems with the bubblers - Ultimately, I found I didn't need to use the aquarium pump, I could get all the gas out of the mixing bottle into the receiving bottle and a consistent 6,000ppm/L by setting the mixing bottle in hot water. So for me, it was an unnecessary step. This is not to diss anyone who does it differently or to say that mine is the only way. We all have our own methods.

Hi Clint good to see you back here again. Pam Michael Steve are the experts lol Im sure they will get to you all soon. Was just letting healthy know where the topic was to make the CDS

I never had any trouble with the "OZONE" stone. the stones Jim used were so cheap so fragile they didn't have a chance with the CDS gas.

I guess the Ozone stone i have is high quality because nothing happened to it. (but i also do not make CDS every week.... )

I like to use the air pump (with the little faucet) and the Ozone stone because of 2 reasons -

1. it takes me 10 minutes to make 6000ppm or 12000 ppm CDS
2. i use less MMS to get to those levels of PPM then what Jim uses - so i save MMS which is harder to get where i live.

By the way, my Ozone stone is not glass stone , it is high quality ceramic stone. no CDS gas or heat will ever be able to destroy it, and i think because i use an air pump there isn't much heat anyway....

Hi Nir,

Glad you had success... when I made my first batch of CDS... I put 1oz each of MMS & CA in a jar ... capped it with a tube running out to the receiving bottle..... then placed the solution bottle in a pot of almost boiling water on the stove. I swear I had about 10,000ppm CDS in the receiving bottle in about 7-8 minutes ... it was that fast. I was stunned ! Cause I was hearing all this 15 minute stuff.... but not on my end.

Now, it made me think that it might depend on the heat being applied to the source bottle ... I don't know.

So... for me... a pump wasn't necessary, at all... cause the CDS simply HURLED itself into the other bottle in no time... AND ... I had to dilute in half.



Megg:

Thanks.. I was just lurking til all the drama died down ....


Pam:

I would really like to know what stone Jim was using... because as Nir sais, there are Ozone stones (which I have) and they are difficult to breakdown .... and if the stone is made correctly, the glass particles that make up the stone should not be able to be broken down by the CDS gas, as they are melted together .... but, that depends I guess on what temperature that gas is getting to be by the time it hits the stone.... just a thought.

Clint

Macaddict08 - the reason i use the pump is because my ceramic stone makes very very very little bubbles, its got so tiny holes that you need a lot of pressure for the gas to start coming out , that resulted in a waste of CDS gas that didnt came through the stone and everything was moving very slow.

with the air pump i can control the size of the bubbles and the speed it goes out from the MMS chamber to the CDS water to bring it to a maximum use of the amount of MMS i am using and the speed i make the CDS.

I like inefficiency

(Jim used air stones that costs about 1.5 dollar each, they were design for aquariums NOT for ozone - they were really bad quality stones for CDS or OZONE)
