I have one in every tank! These are so great!
I’m really impressed with this filter! It has great water flow and does an excellent job keeping my aquarium water clean and clear. It was easy to set up, runs quietly, and the 400 GPH flow provides plenty of circulation for my tank. The UV feature is a great bonus and gives me extra peace of mind when it comes to maintaining clear, healthy-looking water. Overall, it feels well-made and performs exactly as I hoped. Definitely a great value for the price, and I would recommend it to other aquarium keepers! 🐠💧

Good investment.
Did exactly what I needed it to. The tank went into a bloom while we were away and the house sitter wasn’t knowledgeable enough to deal with it. We got home on a Monday, this was delivered Wednesday and by Saturday with 1 25% water change it was crystal clear again. Now it’s off and ready for the next battle

Great product
I recently purchased a UV filter for my aquarium, and I couldn't be happier with the results! Within just three days, the water went from cloudy to crystal clear. It was incredible to see how quickly and effectively it worked. My fish seem healthier, and the overall appearance of the tank is much more vibrant now. The setup was straightforward, and the filter runs quietly, which is a huge plus. I highly recommend this UV filter to anyone struggling with cloudy water or algae issues—it's a total game changer!

This filter saved my tank - 100/10
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.

Poorly designed UV filter ...
I had a previous version of this and bought a second so called improved. The UV light is difficult to get in place, the bottom of it, which you are blindly putting in, and has to be exactly in the right spot. The sponge filter will need regular cleaning so clumsiness of this is a regular inconvenience. The friction fit of the top to the bottom means you will need to carefully arrange this in the tank or the bottom could fall off? The inlet for the air hose is again a friction fit, and so loose it does not stay in place. And lastly, the air hose they provided is so flimsy it's got kinks, and pinches in it even from shipping. It was frustrating to put together so from an ongoing maintenance point of view it's just not usable IMHO.
