Factors to Consider When Buying The Best UV Sterilizer Freshwater Aquarium
Different kinds of sterilizers are available in the market, showing various features to give you the best sterilizer out there. Because of that, choosing what is best for your aquarium might be difficult. Here are the things that you should consider when getting your own sterilizer.
When getting a UV sterilizer, you need to know that not all sterilizers have equal strength in getting rid of bacteria or even viruses from the water. Some low-priced sterilizers can take away algae in the water but cannot eliminate bacteria that may harm your fish.
When it comes to sterilization level, most UV sterilizer falls between two categories namely:
This Type is a strong and cheap UV sterilizer that is designed to eliminate the majority of bacteria and viruses in the water. Many sterilizers that you see are Level 1 because they run effectively and operate in higher flow rates to rapidly clean your whole tank.
On the other hand,level 2 sterilizers are more robust in cleaning than level 1 and operate in low flow rates. It is also equipped with more concentrated light that can eliminate hard-to-kill viruses and multicellular parasites that cause fish infections.
The Correct Size
The UV sterilizers that you see in the market have different sizes, and it conforms to the bulb's power and its flow rate. Moreover, the effectiveness of the sterilizers is affected by its UV light wattage and water flow rate. Preferably, you should buy the sterilizer that can easily process the water in your tank after an hour.
How Much UV Light Is Transmitted?
You can measure how much of the UV light is being transmitted into your whole tank. If it is 100%, then it means that there is no hindrance in the UV light sterilization process. However, a lesser amount means that the light is not transmitted correctly.
If the water is dirty or cloudy, then it can affect the transmittance of the UV light. It's better to use filters to take away any debris first, followed by your UV sterilizer to guarantee high light transmittance.
However, if you still have a problem with the transmittance even with the addition of filters, then you need to get a UV light with a higher wattage to ensure that the water will be properly sterilized.
UV lamps or Ultraviolet lamps use mercury to light up, and it should be at low pressure or medium pressure to work. Majority of the sterilizers you see utilize low-pressure UV lamps because of their high performance.
However, low-pressure UV lamps only work effectively above 20 degrees Celsius or 68 degrees Fahrenheit. Thus, it is crucial to maintain temperature in the tank. You can opt to get a higher wattage UV light or decrease the flow rate if the water in your tanks is cold.
The Diameter of the Sterilizer
If the sterilizer's diameter is higher, then the water will be exposed longer with the UV light. However, keep in mind that increasing diameter would then decrease the chance for water farther from the light source to be clean effectively.
On the other hand, a narrow diameter can sterilize more water, but it entails higher electricity consumption. If you want to have a good quality treatment without a problem in the flow rate, then it is best to go for a diameter of 3 to 5 inches.
The quartz sleeve is used to add temperature in the UV light. This is important if you have a low-pressure lamp because it works better in higher temp. Also, quartz sleeve almost transmit 100% UV light increasing transmittance in the tank.
If the tank’s temperature is already warm enough for the low-pressure lamp, it's suggested that you do not use a quartz sleeve since it will not be beneficial anymore. The sleeve is also difficult to clean and may hinder contact of water to the sterilization lamp.
Make sure to know first what things you want to remove in your tank before you choose a UV light. After all, the majority of UV lights can quickly kill microorganisms. But if you always have outbreaks, then it is better to get a level 1 or 2 sterilizers to destroy the source.
If the infection persists, you can also adjust the flow rate to make sure that the exposure of the water with the light increases. Add a filter as well to make the transmittance better in the tank. This will make the water cleaner and will stop other microorganisms from spreading.
