Oxidising Agents, H2O2, Potassium Chlorate Etc

Oddly enough, I'm familiar with KClO3 from other applications. I would think that in this application it would be problematic. It isn't very soluble, and the chlorate ion (ClO3-) decomposes in a complex manner. One of the intermediates would be hypochlorite (bleach). Ideally one would wind up with KCl and O2 as the final decomposition products. But it wouldn't be that simple. Add CO2 into the equation and things can get complex, with carbonates and/or bicarbonates resulting (alkalinity).

Were I shooting for oxygen release I'd stick with hydrogen peroxide, judiciously applied. That is a way simpler decomposition reaction with oxygen released and water being released. One would want to be sure that pure hydrogen peroxide solution is being used, and not something with stabilizers or other additives.

Thanks for coming in, I had hoped for input like this-It is also the reason I am not trying this on my girls. I still come back to the fact that these delivery systems are being developed at great expense with the sole aim of creating mini ecologies where fish, plants and corals can not just survive but thrive. Looking at the plants being treated, I see truly healthy organisms flowering/fruiting, living only on what they are fed, and weak European winter sun.
What I must do today is to set things up and trial only the pot chlor system this month, and the co2 following that, before trying them together. it was daft to sling them both in at once, although the Ph now seems under control and the plants do not seem to have suffered at all
As well as healthy big cropping plants, the possible prize of being able to induce flowering out of season is at the end of this. Which would be nice.

I have re-filed the tank with the following
30litres tapwater
45ml Floragro
30ml Floramicro
15ml Florabloom
7.5ml Hydrogarden BioLink plus (microbe sauce)
I calibrated the PH tester (Adwa-100)
It all Ph'ed to To 6.8
I added Growth Technology PH down and re-tested, PH was 6.1
I added 1 CO2 tablet and re-tested 1hr later, PH 6.8
The tablet has now (3hrs) dissolved and the PH is 7.1.
I will now add PH down and re-test in 24hrs

PH down added 24hrs ago and tested at 6.1
re-tested this morning and it is steady at 6

I don't get the point of CO2 tabelts in the resivoir , i thought plants only absorbed CO2 through their leaves and no where else .

Follow the links.

In my grow tent I am using the co2 tabs(1/2 at a time) in a capped bottle with a little water in the bottom and a diffuser made of filter paper- the bottle pressurises, and the co2 leaks out slowly. I have hung it about 15" above the plants and refresh it every morning-it must be better than nothing. When i have seen how the Chilli plants react, then I will use it in solution.
BTW they are doing just fine.

Checked PH this morning, steady at 5.9. Plants doing extremely well.

Chilli plants have now doubled in size, PH remains stable. Plants are fruiting even with low natural light levels

Hi All.
Fascinating M8, its nice to see folk experimenting, and thinking.
I've been thinking along not to dissimilar a line myself. (infact only tonight I found two small packets of Potasium Chlorate tabs, given to me a while ago by a friend, the reason I got onto this particular thread in the first place). Although I haven't used the Pot Chlor Tabs.
I suspected the chlorate may be alkaline, as chlorate figures in bleach as I recall.
The Co2 root absorbtion is especially interesting.
I already run an Ozone generator, (split, half into my res, for bacterial control/oxygen supplimentation, and half into my extraction system, for odour control.
and in the future intend to fit Co2 enrichment, I was thinking about feeding the Co2 strieght into the res with a glass ceramic diffuser, (that I already have), the Co2 that doesn't diffuse into solution will outgas from the surface`of the res, and the circulatory fan will mix this into the environment.
this was my thinking anyway, although I'm a while away from the Co2 enrichment, although I may press ahead for this summer, as one can run the higher temps with Co2 enrichment.
Its amazing how little enrichment one needs, to raise ambient Co2 levels (around 350-400 ppm) to the optimum of (I think) 1500 ppm.
At 1500 ppm the enrichment is 4-4.5 times ambient, it would be suprising if this didn't impact the plants growth rates EH???
Toodle Ooo

I use H2O2 in my solution.
Hand-water potted in coco-coir.
They seem to enjoy it =]

Can't wait to get my hands on some food-grade H2O2 so I can quit buying this 3% nonsense.

but I thought adding Co2 to the water changed the PH. So if you did the test Co2 vs no Co2 and there was a ph problem corrected by the co2 that would be an issue. I think.
