The Best UV Sterilizer for Aquarium (Review) in 2021

When the water of your aquarium becomes cloudy or green in color, it’s extremely likely that your current filter isn’t handling its job properly. The COODIA Internal Green Water Killer Filter has the ability to clean any tank that has up to 75 gallons of water inside of it. Installing this water filter will ensure that your fishes or other aquatic pets have clean, clear water.

The filter starts working immediately and will show noticeable results within a week of installation. After that week is over, users will notice that the filter continues working and clearing the water inside the aquarium that it’s in. Typically, it takes a maximum of two weeks for the water of the tank in question to go from cloudy to completely clear and cleaner that you may have ever seen it.

SunSun Group was established in 1998, and with just 20 years in the business, they have been able to manufacture over 100 types of products for many to benefit. They have multiple factories and offices which oversee the factories from Hong Kong, to the USA and with over 28,000 employees, SunSun products come out with exceptional effectivities. One of such products with high functioning capacity, is the SunSun Group JUP-01 UV Sterilizer.

This sterilizer features a powerful technique towards eliminating free-floating algae in an aquarium, as well as other bacteria. This pond UV sterilizer possesses a pre-filter sponge which adequately traps floating debris in the water, in order to ascertain the most effective UV penetration for maximum results. This process guarantees that all obstructions are out of the way, and a clean and microorganism-free aquarium is guaranteed. What’s more, the SunSun Group JUP-01 UV Sterilizer also features an extremely compact appearance, suitable for either horizontal or vertical mounting in the aquarium and also requires no circulation pump to be attached, as this UV sterilizer was perfectly crafted to have all the pre-installed features for direct use out of the box.

Before using this product, the seller advises that you must remove a sponge from inside the product that is placed there to ensure that the Submersible Filter isn’t hazardous during transport. Leaving the sponge will only stop the filter from functioning correctly. The small motor that is a part of the filter’s design creates a, somewhat loud, whirring noise when active. Once the filter has been submerged into the tank, you should not hear this sound anymore.

This Submersible Filter by Coospider is designed to complete four different tasks while it’s working. It acts as a water and air pump, a water filter, and a tank cleaner. Though the filter won’t be able to handle algae that is growing on the décor inside the tank (as this growth won’t pass through the filter to be eradicated), it will clean anything that processes through its filtering system. You’ll have clearer tank water in a matter of days.

Though our readers may be confused at the sight of this UV lamp, but we assure you that it’s among the best product solutions for sterilizing the water of your aquarium. This submersible lamp by Coospider works by using UV light to sterilize the water instead of chemicals. It’s best to combine the light with a standard water filter and you should also immediately separate all of your fish from this product. No fish should be able to swim up to or near the submersible lamp because it will be detrimental to their health within seconds.

The 254nm wavelength of the light helps remove the green tone of your aquariums water by eliminating bacteria and other nastiness. It should, over a period of a week or two, be able to fully clean the water of your tank until its clear again. This will only happen if you use a water filter in tandem with the submersible lamp, and it will not be able to treat the algae growing on surfaces in your aquarium.
