Submersible UV sterilizers are devices that use ultraviolet radiation to eliminate germs and potentially harmful pathogens which might contaminate aquarium water or small garden ponds. These are highly effective in eliminating microorganisms such as algae too and are particularly useful if the fish you own have a weaker immune system.
Usually, they are characterized by the maximum capacity of the tank they can efficiently keep clean and sterile. Buying a product meant for a very large aquarium but using it inside a small tank will occupy precious space and will raise the water level, while, on the other hand, having a low-power UV sterilizer and using it for large quantities will reduce its efficiency.
There are products available for sale for all types of aquariums, no matter how large, professional items which can treat large quantities of water and disinfect it with great efficiency. These are recommended for big tanks, such as those found in biology museums or professional breeders. Pricier than the average household variants, these are rather bulky and might even be too large to fit your aquarium.
Usually, products for the everyday capacities belong to two categories: 75 gallons and 150 gallons. Both are pretty much similar in price, the main difference between them is how much water they can treat per hour. It is common to find 13-watt lamps in the larger and more powerful variants, while those for small tanks only use a 9-watt lamp. However, both are equally effective for their category.
You might also want to find out more about some tools that would allow you to take samples of water from the tank and have them analyzed, things such as small and accurate pipettes, reliable dropping pipettes or a versatile multichannel pipettor.
The sterilizer is only responsible for eliminating the pathogen agents from the water. It does this by using UV light, which effectively destroys them. In order to obtain an efficient sanitization, you have to recirculate the water and to also provide enough exposure to make disinfection powerful enough.
For this, you need a water pump and the subsequent tubing. Furthermore, to eliminate the debris that might reduce exposure, a mechanical pre-filter for trapping them should be installed to purify and clear the water before passing through the UV area. This would imply extra tubing and quite a headache.
This is why a modern good submersible UV sterilizer includes all these elements in the same product. Water is absorbed through the lower part, and the bars prevent debris from being sucked into the system. It is then circulated through a mechanical filter which traps larger particles, and only then does it pass through the front of the UV lamp, which sterilizes it.
Once the process is over, the water is pumped back into the tank, entering it through the nozzle. Adjustable flow sterilizers are a good choice too because they allow you to efficiently specify the amount of water to be processed in one hour.
Other features which might be included with some products are suction cups to help you install them inside the aquarium, spare parts, and some tubing if it is required. Sometimes, spare lamps are included – these should be changed yearly, in most cases.
Lock-on clips for easy filter removal and change, as well as for surface cleaning, are also provided sometimes. These make maintenance easier but do not influence the overall performance of the machine, as long as regular cleaning is done.
Professional sterilizers, however, used for large aquariums, can cost a lot more but these also include a lot of extras which might be useful in certain scenarios. It is recommended that you buy the product most suitable for your needs, in accordance with the capacity of your fish tank.

In order to sterilize the water, it uses a compact UV fluorescent lamp built in a quartz sleeve which is airtight, allowing a very high transmission rate. It helps greatly in eliminating disease-causing germs or bacteria. The integrated pump and mechanical pre-filtering sponge are useful in eliminating small particles such as sand or dust, making the water look clear.
After the water has been circulated through the particle filter to trap debris, it is directed towards the UV without any bypass. The sterilizer features a quick-release cap mechanism which provides easy access to sponge replacements and regular cleaning schedules. Removing organic matter that might build up on the quartz sleeve is also simple and fast.Buy from Amazon.com
