sochting oxydator and cupramine

[johnthehermit]

Hi,
I have a question regarding a Sochting oxydator. I have just purchased one to use in my sump after siporax to add oxygen before the return pump and I'm wondering if it would be possible to use one in a QT while treating with cupramine. Would the oxidator (which uses hydrogen peroxide) affect the copper treatment or be of benefit?

thanks

John

It might. Seachem won't reveal exactly what cupramine is.

I've e-mailed Seachem, let's see if they reply.

Just done a little research and it seems there is a reaction between copper and H2O2. It does oxidize the copper, so it may cause the copper in Cupramine to precipitate out of solution. I do hope I get a definitive reply from Seachem, but if not I will only use the oxydator before and after treatment if required.

What do you expect hydrogen peroxide to achieve?
My understanding is the oxidator is designed to release H2O2 very slowly and raise O2 to levels that won't affect livestock.
I think it won't have the same sterilising effects as when dosed directly, if that is what you are aiming for.

It's the increase in o2 that I'm interested in. I think it may be beneficial in a QT particularly if a fish is infected with white spot or other parasite or infection that affects respiration. If any other benefits occur, as some have reported, would be a bonus. But it is the increase in O2 that interests me primarily.

Fair enough. I think there is nothing bad that can come out of it.
On the other hand, I don't think it will contribute to their breathing, because they aren't struggling due to lack or low O2. Also, unlikely to affect parasites, because the dosage o H2O2 required to kill them, will also kill the fishes when exposed long enough.
Still worth a try.

No, that isn't true. Copper is already in the +2 state and will not oxidize further. Oxidizing copper (from metal to +1 to +2) also does not make it less soluble.

My concern is potential oxidation of the "amine" to an amine oxide or other compound which may cause it to be released from the copper.

The WS parasite attacks the fish's gills and the fish often dies through asphyxiation. Using an Oxydator is akin to putting an oxygen mask on the fish allowing it breath more comfortably and a great aid to the fishes recovery from WS. The fish does struggle through lack of oxygen when under attack from WS that is why they are seen with rapid gill movement as the fish tries to force more water containing the oxygen it needs to breathe through its gills.
