What this means is a true level one capable UV Sterilizer is a useful tool, but also NOT the solution to all your aquarium or pond problems. It will not eradicate all dinoflagellates in your marine aquarium, no matter how good your UV Sterilizer or how slow your water is run through the device. Nor will it make up for poor pond or aquarium filtration, feeding, water chemistry, etc.!!!!

The picture below further pictorially displays how a TRUE UV Sterilizer can help not only with clarification of an aquarium/pond with an assumed healthy bio filter (which should be but a minor reason to own a TRUE UV Sterilizer). It is noteworthy that clarification/green water control is much more effectively accomplished via a True UV Sterilizer over the majority of UV Clarifiers marketed as UV Sterilizers.
HOWEVER, and , a TRUE UV Sterilizer helps with disease prevention & Redox Balance (via proven lowering of oxidative stress) when properly connected (meaning flow rate, pre-filtration, etc.) and properly maintained by replacing with high output UV lamps/bulbs (not the economy replacement lamps/bulbs sold by discounters that have as little as 25% of the necessary UVC as a HO UV lamp).
This is the thrust of this article, as while it is certainly a good tool for green/cloudy water especially in ponds (assuming the bio filter is healthy), it is this Sterilization/Redox Balance aspect that years of hands on use in 1000s of applications has made the difference.

Of course there is the preponderance of UV Sterilizers offered both online and at many Aquarium/Pet Stores that at best can only clarify, such as many of the AquaTop, Submariner, Green Killing Machine, etc. So using one of these to rate all UV Sterilizers is intellectual dishonesty. It's Week 14 of 52 Weeks of Reefing, and this week we are going to talk UV sterilizers. We will discuss what they do and don’t do, setting realistic expectations of how they function, how to size and properly set up a sterilizer, answer some common questions, and show you the installation for the BRS160.

UV sterilizers are probably one of the most hotly debated topics in the hobby with reefers firmly divided in their position of UV sterilizer’s effectiveness in closed systems like a reef aquarium. Sterilizers are designed to protect your fish against harmful waterborne pathogens like bacteria, protozoa and viruses. In a closed system like a fish tank these pathogens can spread quickly and easily wipe out the entire tank's population.

So where does all the hotly contested debate come from? It’s mostly from a complete misunderstanding of the expectations of what a sterilizer is going to achieve in a reef tank. The sterilizer is only designed to reduce the chances of or slow the progression of an outbreak so you have time to research and treat your fish before they are all affected.

The sterilizer is in no way even close to complete protection from an outbreak and of almost no value treating an already existing disease, algae or cyan outbreak. Once the bacteria, protozoa or virus has settled on the fish, defeated its immune system or natural resistance the sterilizer is going to do nothing to protect that fish from the progression of the disease. The UV sterilizer is simply there to reduce the chances that you ever have to deal with an issue like this and if you do give you more time to do something about it. Regardless of the side of the debate you find yourself on this is a statement that almost everyone can agree with.

There is an endless amount of zoos, public aquariums, aquaculture facilities and marine wholesalers that are in the business of protecting their fish and they use UV sterilizers precisely for this reason: To protect the fish and keep them healthy. These are industries where losing animals just isn't an option and survivability equals profitability. The Emperor Aquatics brand of sterilizers in particular is popular in these in critical industries.You don't have to do without a UV-C sterilizer if you have a saltwater aquarium. The sterilizer ensures that even sensitive corals won't be attacked by bacteria. They won't suffer any tissue damage, which means you'll have a good chance of increasing your coral through fragmentation. You'll also notice a decrease in fungal infections as well as bacterial infections and skin diseases. The sterilizer will also help avoid cloudy water and the lower germ count in the water means you won't have any issues breeding fish and other marine life.There are myriad uv sterilizers on the market for use with aquariums. Some are HOB, others are plumbed into the output tube of your canister filter or sump, and still others are suction cupped to the inside of your aquarium.
