I don’t usually write product reviews but I had to for this filter because I am so blown away by what it did for my tank. I was at a loss and trying all the chemicals, filters, and natural remedies that I could find to fix the algae overgrowth and smell in my tank. Frequent water changes, biomedia, a plecco, the works. I was about to give up and start a whole new tank but I decided to try this filter and it saved my tank in 48 hours. The water went from completely murky and green to crystal clear. The before and after pics that it shows are no joke. Here are mine. Literally taken 48 hours apart. I took my secondary sponge filter out & now only have this one. Recommend 100/10. It’s very strong though so I don’t recommend if you have fragile fish that need calm waters. I decided that mine will just need to learn to deal with the rapids because it works so well :) 45 gallon tank with 3 XL goldfish & a plecco but upgrading to a 60 gallon tank in about a month. Confident this filter will work there as well.

THIS IS A REMARKABLE FILTER WITH A U-V LIGHT FOR AN AQUARIUM THAT IS HAVING TROUBLE WITH CLOUDY WATER. I WAS HAVING TROUBLE WITH BROWN ALGAE ( WHICH IS NOT A ALGAE AS SUCH ) AND WAS DESPERATE . I HAD TRIED EVERYTHING TO ALLEVIATE THIS PROBLEM SO I DECIDED TO TRY THIS FILTER AND THE RESULT HAS BEEN NOTHING SHORT OF MIRACULOUS. IT TOOK A COUPLE OF WEEKS AND I CLEANED THE FILTER ONCE, BUT NOW THE WATER IS SUPER CLEAR AND MY FISH ARE VERY HAPPY. I HAVE CAT FISH ONLY AND THEY CAN BE MESSY EATERS BUT THIS FILTER DOES A TREMENDOUS JOB. I DO A WATER CHANGE EVERY WEEKEND AND VACUUM THE GRAVEL AND I'M VERY HAPPY WITH THIS PRODUCT. I AM ALSO NOT OVER FEEDING MY FISH . I EVEN NOW HAVE ANOTHER BABY CATFISH WHO IS HAPPILY SWIMMING AROUND IN MY CLEAR TANK ! GREAT PRODUCT .

Excellent! Works as advertised and cleared a persistent algae bloom in a matter of days. Not overly loud or disruptive to the fish. Very pleased.

I’m really happy with this aquarium filter. It was easy to install and started working right away. The water in my tank cleared up noticeably within a day or two, and it runs fairly quietly compared to other filters I’ve used. I also like that it has the built-in UV feature to help keep the water clean. Overall it works great for my tank and seems like a good value for the price

Okay to be clear on this product, I am not paid for this review whatsoever. I see all the review discrepancies and this product is amazing but you have to have it perfectly in the right placement. This UV filter is a life saver for any tank, however, it’s quirky in the sense that it needs to be a specific level in your tank and with a specific amount of water levelization or it will stop working all together. You do have to play with the placement inside the tank (move it up and down a tinch) and play with your water levels (volume wise as adding more or less water to your tank) a little but it will come back to life 100 percent. Use an extension cord as well to allow more access to move it accordingly. When you do this— it works perfectly. The UV additions to my canister did not do the job this guy does.
