What is an Aquarium UV Sterilizer and How It Works?

For anyone who does not know the aquarium UV sterilizer, it is a piece of equipment that can improve the clarity, the cleanliness, and the overall health of the aquarium. They are very commonly used in the ponds, but they can also be used in the aquariums to eliminate various water-borne microorganisms such as the free-floating algae.

And the concept is pretty simple. It is a tube that contains a fluorescent lamp that produces the light of a specific wavelength. The water flows over or around the bulb, and as the light hits the bacteria or algae, its DNA mutates, which prevents them it from growing. The result is cleaner and clearer aquarium water.

How to Choose a UV Sterilizer for Fish Tanks?

If you want to choose the best UV sterilizer, there are a number of features to consider before making your purchase. Thus, I am going to introduce you some necessary points that you should keep in mind carefully. Let’s check it out!

The size of the tank

The first element to consider when choosing a UV sterilizer for aquarium is the size of your aquarium. In particular, you should clarify whether the UV sterilizer is suitable for your tank or not. You should carefully check the model to confirm if it fits your aquarium perfectly.

For instance, you can identify the capacity of your aquarium and then compare with the figures of the UV sterilizer. By doing this, you can have the best items for your tank no matter its capacity is 50 gallons or even 150 gallons.

Saltwater and freshwater

Moving to the next factor, you should think about the type of water that you are aiming to clean with the UV sterilizer. For every model, they are designed for either saltwater or freshwater. Or they can be made for both types of water.

And well, my advice is that you should look for the items that are suitable for both saltwater and freshwater, which is the best choice for you. By this way, you do not have to worry much whenever using the specific UV sterilizer for aquarium that may include different types of water.

The design and the weight

The last matter that you should always remember is the design as well as the weight of the aquarium UV sterilizer. In case you are having a small or medium tank, I highly suggest that you should buy a UV sterilizer with the compact design. But do not forget that this type of UV sterilizer should provide sufficient lighting for the plants and the fish in your aquarium.

Following my tip will definitely help you clean the tank water as well as give your beloved creatures the most comfortable environment. Also, make sure that you will select the models which can be easy to mount or hang on the aquarium.

Things to Be Aware of the UV Sterilizer

There are two common designs for these UV sterilizers. Some of them are self-contained and hang inside the tank. They have their own powerhead and are very easy to install. The larger versions can be plumped in line with your canister filter.

Plumbing them is really simple, especially if the size if the tubing from your canister filter output matches the size of the intake and output of the sterilizer. And in general, the longer the water is being exposed to the UV light, the more effective it will be.

This is referred to as the contact time or the dwell time. Moreover, there are several factors that can influence this. One is the flow rate of the filter. Second is the size of the aquarium which, along with the flow rate, determine the turnover time of your filter.

The third point is the size of the sterilizer and the length of the bulb. And fourth is the power rating of the bulb. As a consequence, if you have a really great filter with a high-flow rate on a big tank and a small or weak sterilizer bulb, then it is not going to be super-efficient at all.

So, my advice is to research what you are buying and read the manufacturer recommendations. Also, make sure to compare them to the specs of your canister filter. Now, there are a few other things to keep in mind with these sterilizers.

The most important tip is that these are not a replacement for the good filtration, the water changes, and the routine maintenance. You should think of them as a supplement to help get you to the next level of clarity. Another thing to remember is that the organisms that are impacted by the sterilizer must actually flow through it.

The UV light has no residual effect and it will not kill the microorganisms attached to the fish, the rocks, and the glass because they do not flow through the unit. And lastly, there are a couple of times when a sterilizer should absolutely not be used.

When first cycling the aquarium, because it can kill the beneficial bacteria before they get a chance to attach to your bio-media or substrate. So, when medicating your tank, as some medications can be rendered ineffective by the UV light.
