UVC Irradiation and Immune Response, Aquarium Applications

UVC irradiation and immune response
This includes human research into BioPhotonic Therapy and UVBI Therapy

Updated 12/8/14

This article/post is meant to expand on my previous article “Fish Immune System and UV Sterilization”. This time utilizing information about UVC irradiation as per human studies and its affect on disease treatment and over all aquatic health.
While the application to fish in aquariums/ponds is somewhat “apples to oranges” in comparison at this point in time, the implications are certainly far reaching as to the affect on Aquatic Redox and fish health.

Since most in depth research is found in human studies due to the costs involved vs. lack of funding in the aquarium keeping hobby as well as the unfortunately common anecdotal comments made about UV Sterilization made by many in the aquarium hobby that are years behind real research; one often needs to go outside the hobby to find good and cutting edge research. In fact I just recently came across this gem of a post of anecdotal bad information from an otherwise good aquatic article: “For me, a UV filter is just a ‘feel good’ device and leads hobbyists into a false sense of security” It is too bad that so many aquarium keepers simply refuse to do their homework, but this is likely to continue considering how lazy many persons can be at times (otherwise how can you explain the popularity of such terrible sites for aquatic information such as Yahoo Answers among many others, or directories such as DMOZ with its outdated directories).

The concept of BioPhotonic Therapy and UVBI Therapy was brought to my attention in an email and phone call by a researcher (Dr. Mamoon Kundi) who found me via my UV and Redox research articles.
One concept is clear and that is that the use of >UVC lamps can affect both the oxidizing and reducing side of the Redox Balance equation that is so important for life.

Studies in UV Irradiation

 BioPhotonic, UVBI Therapy  DeviceIn these studies, blood is irradiated (via different methods), often with very pronounced results. William Campbell Douglass, MD, who treats his patients using only alternatives and has written several books on these subjects, wrote a book called Into the Light, where he recommends Photoluminescence Therapy for the following conditions:
• Immune deficiency problems
• Viral Infections (hepatitis, respiratory, etc.)
• Pneumonia
• Non-healing wounds and wound infections
• Emphysema
• Inflammatory Processes: fibrositis (inflammation of, mainly, the muscle sheath), bursitis, iritis (inflammation of the iris), pancreatitis, etc
• Autoimmune diseases: rheumatoid arthritis, AIDS, etc.
• Osteomyelitis (bacterial infection of the bone marrow)
• Septicemia (virulent infection of the blood)
• Cancer (experimental at present)
• Peripheral vascular disease
• Most vascular disease
• Thrombophlebitis (inflammation of a blood vessel that results in blood clots)

Implications of this research as per aquariums/ponds
While we as aquarium and pond keepers are not too likely to utilize these UV blood irradiation therapies on our fish, this still has implications as to how a UV Sterilizer can be an important part of ANY aquarium keeper’s (or pond keeper) filtration system in that this latest research backs up many of my own tests and research going back to the early 1990s. The implications of the affect of the UV irradiation on how it may not necessarily outright kill pathogenic microbes found in the water column, however it certainly allows for an improved fish immune system response to pathogens, which is one of my earlier findings as well (although I did not know the whys of my test results back then). The affect of UVC irradiation also has a positive affect on Aquarium Redox Balance which is also important for aquatic health.

It is also noteworthy that even with regular water changes, and the addition of mineral cations that both replenish the electrolytes from the reducing side of the equation, this is only a part of what the human studies indicate, and that is while the use of minerals and other antioxidants is certainly a good idea, when there are stressors such as disease pathogens, immune deficiency problems, etc. there is a need for additional ongoing Redox Reduction to counter free radicals that a UV Sterilizer provides that mineral cations cannot provide adequately.

The bottom line is this is just one more piece of evidence that a correctly installed UV Sterilizer should be part of every serious aquarist filtration system, especially those who keep expensive, rare, or delicate fish.

Fish Immune Health and UV Sterilizers


Updated 3-10-19

Fish Immune System (Including Anti-inflammatory), Redox, Oxidation, and UV Sterilization

UV Sterilizers, Terminator, Custom, Gamma

I have seen many comments posted in various places on the internet claiming that running a UV Sterilizer 24/7 will weaken the immune system in fish in part by creating a sterile environment.
I have tried to find more information as to how this myth got its start and the best I can come up with is that many are equating UVC radiation (emitted in UV Sterilizers) to Ozone produced by Ozone Generators.


Aquarium Ozone GeneratorFirst even though I have not found an Ozone Generator as effective as most UV Sterilizers for disease control (& Redox), even then when properly used the Ozone is not added to the aquarium.
However more importantly is that a UV Sterilizer keeps ALL UVC irradiation inside the unit and this reaction actually breaks apart free radicals and other oxidizers such as Ozone (similar to the reaction of Ozone and UV light energy in the upper atmosphere of Earth).

What is most important to note is that a properly installed UV Sterilizer will IMPROVE a fish’ immune system by creating a better Reducing Redox environment in the aquarium after water has passed through the sterilizer (providing it is a reasonably good unit such as the TMC Vecton/ Advantage UV Sterilizer, the AAP/SunSun Quality Compacts or other higher efficiency, UV Sterilizers.

See these product resource links:
*AAP/TMC Premium High Dwell Time UV Sterilizers for Aquarium & Ponds(Category A)
*AAP Compact UV Sterilizers/Clarifier (Category B)
*TMC Next Generation Ozone Generator from AAP

Here is a quote from "Aquarium Redox Potential":
"A proper Redox Potential improves the health of humans AND fish. A Redox Potential in the +125 to -200 mV range in human studies has been shown to have the same affect as anti-oxidant preparations such Vitamin C".
As well, a Category A or B UV Sterilizer improves Redox Balance via COSTANT removal of oxidizers in the water column thus DIRECTLT lowering oxidative stress in fish.

This picture of a controlled test where by an oxidizer (Potassium Permanganate) is added to the water demonstrates this ability. The control tank retains the color of the Potassium Permanganate much longer than the tank with just Category B UV Sterilization ('Category A' Sterilization will clear it even quicker, although few aquarium/pond UVs are 'Category A' any more with the AAP Vecton/Advantage one of only a couple of brands):

Aquarium UV Sterilizer lowering oxidative stress in fish

In medical studies the enhanced oxidizing environment can facilitate the binding of pathogens or antigens to effector cells (a type of lymphocyte that are actively engaged in secreting antibodies) leading to a hyper-responsive innate immune system.
Previous work has shown that an oxidizing environment leads to enhanced release of super-oxide and nitric oxide, activation and translocation of nuclear transcription factor and enhanced production of cytokines (proteins and peptides that are signaling compounds produced by animal cells to communicate with one another). The creation of a markedly reduced environment by addition of antioxidants blunts all of the above primary responses of the innate immune system."

In studies using human blood therapy, the use of UVC to irradiate blood, these are just a few of the findings:
*Improved circulation and oxygenation of tissues
*Anti-inflammatory effects
*Stimulation of the Immune System
*Increased Tolerance of the body to Chemotherapy and Radiation
*Cardiovascular protection
*Powerful Anti-Infection Properties
See this article for more: Oxygen Healing Therapies with UVC

It should also be noted that a True UV Sterilizer cannot create a sterile environment as it cannot reach all aspects of the aquarium such as gravel, filter media, and the fish internally!

It is unfortunate that these false statements are still widely circulated, I recommend reading this article about UV Sterilization for more:
Ultraviolet Sterilization in Aquariums and Ponds

Or this article about Aquarium Redox:
Aquarium Redox Potential

Or even this article about Aquarium Calcium, GH, KH, pH (as this is also an important aspect as well to a healthy fish immune system):

Finally, if you have a properly set-up aquarium or pond UV Sterilizer, it is important that you change your UV-C Bulb once per six months for most aquarium applications and once per year for most pond application (six months in warm year round ponds).
