Soching Oxydator tests.

[Randy Holmes-Farley]

Your explanation for the drop would suggest the oxydator without peroxide would cause a drop by catalyzing an O2/ organic reaction.

That might or might not happen, but folks just dosing peroxide without an oxydator see a drop, which doesn’t seem explainable
by a reduction in O2 as O2 reacts with organics.

Not my explination. I took it from the net as an explination given nothing more. I am.no scientists just a hobbies who trys things and notices a reaction often anecdotal but in the case of ORP reduction using an Oxydator, something I have recorded on a number of occasions. Why, I admit is beyond my knowledge.

An oxydator is supposed to keep the hydrogen peroxide fully inside its device, at least by some claims, though i doubt it that is true.

Just dosing it allows it to contact organisms and potentially impact more of the tank, even if a UV helps break it down.

You suggest the peroxide plus UV helped velvet by UV alone did not? Not doubting either way, just asking.

The UV had been running 24/7 when the outbreak developed. The velvet was most visible on my purple tang, but all of the fish were swimming in front of powerheads within 2 days of me noticing the purple tang's symptoms.

I caught most of the fish with a trap and gave them a 30 min bath in 5ml H2O2 / L of SW and started dosing H2O2 to the DT the same day. I lost a ruby red dragonet which had not been caught for the H2O2 bath, but all other fish survived and were swimming around normal and healthy within a week. I'm not sure when I'll stop dosing H2O2, as for the time being it's cheap insurance and none of the corals or inverts seem to mind.


On a related topic, has anyone heard of fish getting gas bubble disease due to O2 supersaturation from dosing H2O2 or using an Oxydator too aggressively?

This old review paper cites 110% supersaturation as a general conservative limit, but also contains data showing 200%+ O2 saturation tolerated by rainbow trout

I've never heard of that, nor do i think it likely except in a massive overdose that could cause other issues. Some tanks get supersaturated with O2 due to photosynthesis, and a skimmer and the tank top (with good flow) do a decent job of blowing off excess O2. Its easier to equilibrate O2 than CO2/pH for technical chemistry reasons (interconversion of carbonic acid and CO2 to blow off or enter the water is a slow process, O2 has no such issue)

Nobody has ever reported eye gas bubble disease on the Facebook Oxydator user forum in all the years its been running.

Yeah, I suspected the cheap test strips wouldn't go low enough to natural levels. It's for this reason and others I always suggest when recommending the % of peroxide and number if catalyst that a close eye is kept on your animals for the 30 mins after adding the Oxydator esp for the first time.
Same with most hobby type test kits which often measure low enough to reflect the natural levels in the sea.

So I see this is an old thread . You recommended 9% to me. Since this post have you come to some concrete conclusions , applications ?

 

[Freenow54]

I started using the model A a few months back on my 150g FOWLR and then on my 50g mixed reef. I noticed almost overnight difference on my FOWLR, the water was and has been kept crystal clear. The film algae on my glass was also reduced. I had to clean the glass every few day, at minimum once a week where it looked too ugly to look at. I use a magic eraser and it was black by the time I was done. Now I still clean the glass once a week by habit but the magic eraser is a light yellow. I replace 6% peroxide once every two weeks, I use only one catalyst. Fish don't seem to mind and the leathers seem fine as well. Less alage growth on rocks and glass. Chaeto doing a ok in sump. My oxydator is in the sump next to the return pump.
I then got one for my reef, same effects with crystal clear water using 6% with one catalyst. Corals all doing fine, water parameters doing fine, RBTA, shrimp, all other inhabitants seem to be doing business as usual. So far I have only seen beneficial effects in both tanks.

I realize this is an old thread ,but any changes or improvements done ? I am deciding on this right now and was talking to atoll in real time. I did not get the chance to ask about what to get for a 100 US gallon tank , with a 40 ( the actual water volume in it ) a 4?

 

[Freenow54]

The manufacturers recommendations are based on freshwater not saltwater. We use higher strength in saltwater tanks.
By doubling the number of catalysts you double the breakdown of peroxide and therefore production of super oxygen as they call it. In the UK Joe public can only buy 12% peroxide but adding more catalysts has a similar effect to increasing the peroxide concentration.

Again old thread but I see that the 4 comes with 2 catalysts so where can you buy more? I have a total volume of about 140 US Gallons is a 4 a good choice ?

 

[Freenow54]

Micro algae and many other organisms produce an enzyme that decomposes hydrogen peroxide. i would say that we are left wondering where the peroxide went, maybe just turned into molecular oxygen.

I realize this is an old thread. I was wondering how you use macro algae ie where you put it ect. I had a bad experience with Cheato in a HOB refugium, It had its own pump , and light. I neglected to think about any maintenance and eventually the " debris " it removed started circulating int my tank almost crashing it > So I would really like to know how to apply it.

I have settled on 9% with 2 catalysts in my 110gallon as a standard background/ maintenance level. If I had say itch in my tank which I haven't had in many years I would go for 12%. However, some animals esp Zoas may well not like 12% and even 9% can affect them. No issues with parasites then 9% and 2 catalysts.

I have the model W in my sump purely so I dont have to replenish the peroxide every few weeks. You could use the model A of course which is smaller using the same % peroxide and number of catalysts. Just means you would need to replenish the peroxide more often.

Thanks much. So sorry again where can you but more catalysts and do they ever have to be replaced ?

If you are in the US ( I am in the UK) I believe the shrimp tank stock Oxydator's and catalysts. You do know the catalysts are " very long lived" according to the manufacturers and each new Oxydator comes with the required amount of catalysts.

I am not. I am in Canada. The one they have is adaquate it says Qxydator A for $ 177 Canadian

 

[atoll]

Wow! $35 canadian more than we pay here for the model A delivered.

Found it on another on line store for $ 150. But I like amazon since hides my info also free delivery . Did not try to go further on the store site to see shipping cost. That is what it is like here for everything with this hidden carbon tax.
