Product Description
What does a UV sterilizer do?
A UV sterilizer is used to control infections by stopping the spread of microorganisms from one fish/coral/invertebrate to another through the water. It is also used in pond applications to control free-floating algae. When operated correctly, free-floating microorganisms will be killed by the UV light. Note that the organisms must be in the water that flows to the UV sterilizer. The UV light has no residual effect and will not kill organisms attached to fish (e.g., adult stage of ich) or rocks (e.g., algae).

In which types of systems should UV sterilizers be used and what are the benefits?
A UV sterilizer may be used in any aquarium, however, in smaller aquariums (less than 24 gallons), the cost of the unit may make it impractical. UV sterilizers are most helpful in multiple tank systems that share a common filter. In a single tank system, they are beneficial in controlling the spread of an infectious disease if one occurs. This is especially true in heavily stocked tanks and those with large amounts of live rock and corals that could make catching and isolating a diseased fish difficult, or the use of certain medications contraindicated. Disease control is especially important when adding new fish to an established aquarium, since 98% of the hobbyists do not use a quarantine aquarium.
In ponds, UV sterilizers are one of the best ways to control free-floating algae, allowing the pond owner to see and enjoy the fish. The UV sterilizer will also kill free-floating bacteria in the pond water.

FAQ:
Q. How do ultraviolet ("UV") sterilizers work?
A. UV sterilizers work by exposing water to powerful germicidal ultraviolet light. DNA and protein links in bacteria are destroyed by exposure to this light.
Q. Does the water become radioactive by this radiation?
A. No. No radiation residual or any chemical residual is left in the water as a result of the UV rays.
Q. Do these systems come in different sizes?
A. Yes. The size of the systems is directly proportional to the flow rate of the water in gallons per minute. The higher the flow rate, the larger the system and lamp.
Q. Does the water have to sit in the UV sterilizer to be disinfected?
A. No. If the system is sized correctly, the water is disinfected as it flows through.
Q. What if the water flows faster than is allowed through the system?
A. If the flow rate exceeds the design flow rate of the UV sterilizer, then there is a possibility that the water will not be properly disinfected. It is important to use a flow restrictor so that the flow rate cannot be exceeded.
Q. How long does the lamp last?
A. The lamps last approximately 10,000 hours. That is why we recommend replacement approximately every 12 - 14 months of continuous operation. After this period, the lamp itself becomes solarized and blocks the rays form entering the water.
Q. Are these systems bigger energy users?
A. No. The 12 gallon per minute model, for instance uses only 39 watts, about half the amount an ordinary light bulb uses.
Q. My water is sometimes cloudy. Is that a problem?
A. Yes. The water that enters the ultraviolet sterilizer must be absolutely clear and have a turbidity of less than 1 NTU. If your water is cloudy, then it must be pretreated.
