UV light recommendations

[Kevin Koloff]

With your present system configuration you need a separate dedicated line for the UV. A low flow rate is essential for these devices.

Seagate does not list that Model number on there website.

Sorry I wasn't clear. I am planning on adding the UV later, and parallel in the discharge piping of the filter

A good uv light works and it will work incredibly fast. In less than a week I went from pea green to being able to see 4 feet down. Its the only safe way I know that will clear up a green pond and keep it that way. Yes you can wait for nature to clear it up but how many months do you have in a summer to wait?

Any uv cheap or expensive will work .I found out only 1 company makes the uv bulbs and even the ballasts for the uv's .I tried even looking it up farther bu of course they are not going to rat out the people they make them for ..So no reason to spend money on the same item you can get cheaper .I got mine from topdogseller on ebay .

I use the Savio UVinex UV lights. They slide directly into the Savio skimmer. Their UV lights had a dangerous history of fires and it has since been redesigned it. I know I could get a cheaper UV light, but I'm afraid to try something not designed for their product, since the history of fires.

Is there anyone here, who has actually safely used a substitute bulb in a Savio skimmer?

UV within a certain frequency range does not reduce oxidative stress as the author of the linked article claims, rather it increases oxidative stress. This is what kills the target organisms. At least that is what all of the scientific papers on the subject state.

At exposures approximate to UV sterilizers, the frequency reduces a variety of oxidizers. A prominent aquaculture treatment usage of UV sterilizers is in-line after ozone generaters so to oxidize the ozone. The ozone basically significantly damages the organics so to allow the UV radiation to fully convert them into pyrogens. This is quite successful in reducing bacterial gill disease. UV primarily kill organisms via its photons mutating organisms at the DNA level, to initiate apoptosis; this is why exposure time is quite important. UV sterilizers, at proper exposure, also reduce chlorine and chloramine as well as oxidative organic agents created by heterotroph bacteria that can be stressful to fish. Impacting these issues reduce oxidative stress on fish, thus improves redox. At the lower frequencies and exposures relative to UV clarifiers, ozone is briefly created as opposed to being destroyed and is one of the reasons why the aquaculture industry primarily relies on UV sterilizers.

Interesting. I bit the bullet and bought my replacement Savio bulb and it's working well. Fortunately I seem to get 2 seasons of use .

Quite curious. Appears you simply googled for "uv oxidative stress" thus your results do not surprise me. Dang, I suppose this is how I should do my research.

I bet doctors find this quite appealing when their patients do this prior to their appointment.

That settles it!

Try not to be so biased in your research querying....

If too impatient to read the entire article, then jump down to the UV irradiation section.

[Meyer Jordan]

Do you know a better method of finding and obtaining access to pertinent scientific research papers? If so, I would be very much interested in using it.
I also utilize Google Scholar.

Curious!
Where in this document does it contradict the documents that I posted links to.
Ozone and UV induce oxidative stress in the target organisms. It does not reduce it.

Yes, rather than being so narrow with your search, by going to aquaculture conventions and converse with those whom practice their trade instead of implying they are "full of it".

The document only references the word "oxidative, oxidation, etc" , in relation to ozone not UV irradiation.

 

[Mitakuye]

Ok, I need to return to my work.

 

[Meyer Jordan]

Maybe we need to define terms.
Oxidative stress-
Oxidative stress, a process caused by free radicals. Free radicals are unstable molecules that damage or “oxidize” cells throughout the body in a process called oxidative stress.
