Thats what I said - that small amounts of other oxygen species may be released. The superoxide radicals will be almost instantly degraded when they hit anything organic. The only thing I was trying to say is that there is very little likelihood that any level of peroxide 'toxic' to shrimp will be in the tank.
BTW - I just quoted their product information - and if you google it - you can see its recommended for many 'shrimp' tanks - so to answer the person's question - its safe....
Some people say they're useless and some people say they're incredible. Some people say they clean your water, some say it doesn't. Is it H2O2 dosing or O2 + H2O? Does it help with algae or not? I question why they aren't more popular in the US if they are as amazing as everyone says, but I'm new to the hobby, so I don't know how trends work in reefing yet.
Cleaner shrimp in particular are very sensitive to H2O2, I believe it's one genus, so it wouldn't necessarily apply to all shrimp species.
Be aware - at room temperature - after opening - peroxide expires after about 3 months. I buy the 12 precent - and keep it refrigerated - they give a time limit with and without refrigeration.
This has been widely debated - and I don't believe its true (at least with the oxydator) - like I said before - its dosage and concentration and how quickly the dose is delivered.
BTW - curious - not wanting to argue - but - where are you seeing this - that cleaner shrimp are more susceptible to H2O2 - besides occasional anectotes - that said 'my shrimp died' and other anecdotes that say 'there is no effect on shrimp'? I tried to look it up for you - to me there is no evidence that cleaner shrimp are more affected than anything else
Anecdotes both ways. I tried looking it up as well. - it just routs you right back to reef2reef, so I've read it several times on this forum. Probably shouldn't have said it so confidently. What I mean to say is that there might be a risk, and is it worth it?
Glad you added the edit to say the description is for FW. However it seems with marine shrimp it may not be that simple. Much I suspect will be dependent on how much peroxide is used. There are videos on YouTube of FW shrimp crawling over Oxydators and in fact seemingly seeking them out. However as we know the composition and density of saltwater is somewhat different and I would urge caution with the strength and number of catalysts when you have saltwater shrimp. Perhaps those who have had shrimps using Oxydators could add their experiences. Personally I have not experienced any issues but then it's been sometime since I kept shrimps in any of my tanks while using Oxydators.
To me - toxins are dose dependent. If you're concerned - try 1/2 the recommended dose - or 1/4. And gradually increase it. The oxydator (I dont see) how it could be a risk. Hope all this discussion helped rather than confused.
I can assure you that if you go OTT with peroxide or the number of catalysts that animals will suffer the consequences. I have had anemones turn inside out when I was experimenting with Oxydators many moons ago. When first installing an Oxydator I always suggest that you watch the tank closely for at the the first half hour to ensure nothing reacts negatively. However, few people reports any negative affects apart from an initial drop in ORP which usually increases beyond the origional reading prior to installing the Oxydator.
I didn’t know this I buy it in 5L containers which last 6 months or more... I use 12% so maybe some peroxide left as I haven’t had to use carbon in years and tank “seems” to be clear of yellowing organics...
I would use a low concentration if you intend to.put am Oxydator inside a canister filter.for 2 reasons. 1/ the peroxiddcwill.last longer and 2/ you dont6want to prevent aerobic bacteria from colonizing the media above. Remember peroxide is a potent bleach and I have never heard of anybody putting one in a canister filter.
Yeah I haven’t heard of it before, so I’ll run it very low 3% 1 catalyst. I’m also trying to place it where it will channel back to the tank fastest with minimal impact on the media above. As the filter is relatively high flow 650L/ hr through an 18L canister I’m not sure if it will last longer or not. it’s also the impact on anaerobic bacteria that is the real unknown for me and if it will completely inhibit it, but then again I’m not entirely convinced of how well siprolex hosts them anyway. i have sufficient LR and sand bed to host them... (I think). I’m running skimmerless as well so, which is another reason to try it for me... do you think it’s pushing the use to far?
Your going into unknown territory with your intentions and not easy to predict. Is there some reason why you want to put it in a canister filter rather than a sump or tank itself?
What amazes me is there has been a product available and well used in Europe for over 40 years with prevent results and yet only in recent years the likes of the US have hardly know about it. I have been telling people about Oxydator's on here and other US forums for many years. I don't sell Oxydator's just believe in them and the technology is provent over many years. Amazes me why so many in the likes of the US haven't heard if them. Mind you if the likes of BRS sold them then it might be different. I personally have been using Oxydator's for over 30 years along with a few friends here in the UK and Europe. They are cheap, efficent, easy to use require no electricity and are cheap to run. Oxydators need no maintenance apart from refilling and after years the catalysts replaced. Oxydators aren't some new fangled contraption here today gone tomorrow.
