  • Crystal Clear Water and Easy to Install
Size: Extra Small - H4F(for 10-45 Gallon)
This UV filter has been a great addition to my aquarium setup. Installation was quick and straightforward, and it started working immediately. Before adding driftwood to the tank, the water was crystal clear and looked like glass. I currently have natural wood in the aquarium, so there is some visible tint from tannins, but that’s coming from the driftwood—not the filter. Even with the tannins present, the water remains clean, healthy, and free of cloudiness. The unit is compact, doesn’t take up much space, and the suction cups hold it securely in place. Water flow is consistent, and the UV sterilization helps reduce green water and other common water clarity issues without requiring constant maintenance. ... show more

  • Product under promises and over delivers. Exceptional product that delivers on its promises.
Size: Medium - S9F(for 55-200 Gallon)
I purchased the 200g version, didn't even use the filter cloth. Said it would clear the water in 72 hours. It did not... It cleared the water in a little less than 48 hours. Absolutely crystal clear! It is a high quality product that under promises and over delivers! It is a quality build and has a good solid feel to it. I could not wait to purchase a smaller one for my other tank. I most certainly will patronize this seller and will spread the word about their product. I stand very impressed! ... show more

  • Worked so good 😊 I’m buying this for my other 2 tanks
Size: Medium - S7F(for 45-120 Gallon)
Omg 😯 my tanks water has been green for awhile now. I’ve tried changing the filter. Changed the water twice and cleaning the tank walls and accessories. Also added Kloud Away and but the green water would keep coming back. It got so bad that I was scared my fish were going to die. I thought I might have to just redo the whole tank from scratch again with new stuff then I saw this product and was like huh 🤔 let me see if the UV light will help. I put it in last night (wish I would have taken a before picture because it was pretty bad you couldn’t see hardly anything in the tank) and I woke up to the clearest tank I’ve ever seen. I honestly didn’t think anything would work. Turned out way more clearer than I expected or even imagine. The water is even clearer than my other 2 tanks. Amazing!!! Recommend 100% ... show more

  • Mostly okay though I miss my tiny bubbles.
Size: Small - H6F(for 20-75 Gallon)
UPDATE1: I had to do a water change today as it was time and I stopped the filter just like I always do to avoid any issues. I changed out the water and filled the tank back up. Once again the aeration stopped working. I don't understand why it's not working though it is rather frustrating as this was one of the things I wanted. I have to say I'm a little disappointed with this. I got this when my old filter system fell apart. The installation was easy and at first it really was working well and I was happy with it. About a day later my daughters told me that it was "spitting" and I went to look. The aeration wasn't working like it was in the beginning. I couldn't figure out why as I hadn't done anything with it. It was disappointing and I pulled the system out and cleaned it (even though it had only been a day) and put it back together. Luckily it was really quite easy to pull out and clean and get back in. After I re-installed it the aeration still didn't work that well though I was able to get it to work a little. I will say the suction cups on this thing are amazing. They old everything on tight. I do with the unit I got came with a flow director like the larger ones. It does look fine in the tank where I have it and doesn't seem to take away from the rest of the tank. For the money I spent I'm not too disappointed and I'm looking forward to see how it works with the UV light to help clean the tank. It does seem to work pretty well overall. ... show more

  • Great product!
Size: Medium - H8F(for 40-150 Gallon)
Bought this to replace a failed filter in my turtle tank. I wished I bought it sooner. It filters the water so much more than the old one. The ability to aerate the tank along with the UV light is a tremendous improvement over the old filter. The tank stays so much cleaner and clear now.

  • Great Filter for My 20-Gallon Tank
Size: Extra Small - H4F(for 10-45 Gallon)
I purchased this filter for my 20-gallon aquarium, and it has been working great. It keeps the water looking clean and clear, and the flow has been perfect for my setup. My fish seem to be doing really well with it, and I haven't had any issues since installing it. It was easy to set up and has been running smoothly. Overall, I'm very happy with this filter and would recommend it to anyone looking for a good option for a small to medium-sized tank. ... show more

  • Fantastic remedy for bacterial blooms
Size: Extra Small - H4F(for 10-45 Gallon)
Does what it’s supposed to do with ease! I had a significant bacterial bloom in my 20g nano reef tank that was getting out of hand. I knew I needed a UV on this system but was on the fence on which one to get. I took a gamble on this, even though I knew it wouldn’t fit in my AIO chambers. HOLY COW! Less than 72 hours after dropping it in the tank and plugging it in, water is Clear! This is not a high quality piece of gear, but it works for its intended purpose and is an extreme bargain over higher end UV systems. If you don’t intend to run UV all the time and need to remedy a current problem, I have no hesitation in recommending this. I have taken mine out for now as I hate having gear in the display area, but I’ll run it from time to time as/if needed ... show more
