Anyone who has an aquarium is aware of the importance of cleanliness of the water in the tank. Otherwise, the aquarium is invaded by the growth of bacteria and microorganisms, which can be the cause of loss of fishes. You would come across internal filters embedded in the aquariums to filter off the impurities in the water. But the question is, are these internal filters equipped to restrict algae growth in your aquarium to ensure the well-being of your precious fishes?
Even a few years back, I thought that using an internal filter would help discard the algae. But I noticed that the fishes are dying gradually even though I was feeding them timely, and the filter was turned on. I was desperate to find a solution, so I approached a pro aquarist, and he asked me,’ do you have a UV sterilizer in the aquarium’? I didn’t know what it was, so I googled it and placed an order on an eCommerce outlet.
I followed the instructions and installed it inside the aquarium and guess what, I saw my fishes happily and healthily growing. Ordinary filters cannot strain out microorganisms, which act as a threat to your fishes’ lives. However, a UV sterilizer makes the most of the UV light technology’s power to eliminate bacteria and parasite freely floating in the aquarium water. If you wish for a thriving aquarium, using a UV sterilizer is a must because it is manually impossible for a regular filter to drive away disease-causing parasites and algae growing in the water.
Since there are many options for UV sterilizers available online, you might find it challenging to select the best one for you. To help you make an informed decision in this regard, I have reviewed the top 10 UV sterilizers available in the UK below.
