Aquarium U-V Filter for 10-40 gal, 132 GPH Swirl Turbo Design Submersible Internal Turtle Fish Tank Filter w/Timer, Quiet Power Pump Air Supply Green Clean Machine Saltwater Freshwater Green Killing

I was skeptical of this. I have a variety of small fish in a 20 gal tank. Plus snails who make a mess. This pump works amazing. I’ve been running it as a pump only with out the attached hose thing on top. I reached out to their customer support to verify it would work like this bc I didn’t like the amount of micro bubbles and noise it made with the hose on as an air pump. They got back in less than 24hours confirming you can use it without the air pump attachment. You can visually see the UV light on. It lights green. I kept the sponge inside bc I didn’t have green algae. My tank was just cloudy and dirty from the snails. I did clean the glass first and stirred the gravel a bit to get things moving. 2 days later. Crystal clear. I do have a hang on the back filter from petsmart that gets nasty pretty quick. This is a great addition for any tank.

My tank has never been cleaner! This bad boy doesn't take up as much space as the previous filter I have used and it was very easy to set up as well as clean. It is also much quieter than my last one. So far everything is working well and I look forward to seeing how long it can last. My fish seem to enjoy the bubbles too. I haven't had it for long so I can't speak on durability yet. TBD

This U-V filter worked great for 2 months then the filter pump stopped working. Buyer Beware.

This is the best filter! although it takes time for the water to clear completely, (about a month altogether), it completely clears all the algae in the tank and makes the water crystal clear. For a few months I was dealing with horrible green water where I could hardly see the fish and didn't know where they were half the time, and this filter did the job and now I can see everything completely! Best filter I've ever had! (It was a game changer to say the least)

Love that it clears the water fast! Especially when we had live plants. But ... I can't seem to get the filter cover off! I've squeezed and pulled from both sides and it just won't budge. Does the unit have to be completely dry to get the cover to move? If I could easily remove the cover, I would give full stars. Oh and don't use with live plants either. They tend to gunk it up so it needs cleaning DAILY. Now that we've removed the live plants, it goes longer, tho I've not noted how long. Make it come apart easier but still stay together under water (a clip, maybe?) and I'd totally love it. I know.my turtle appreciates clear water in her tank.

Such a great product that keeps my fish tank clean

You have to clean the sponge alot ! It fills very quickly , the water flow is really nice. Very powerful , Its not noisy at all. Overall a good product personally I just wish the sponge absorbed better , washed better!! But if your looking for air flow its definitely the one !

Highly recommend this uv-filter. Works great. I have been running the filter and UV light 24 hrs a day for 4 days. What difference it has made. After the initial 7 days I will change the UV light to only run 3 or 6 hrs a day. I was struggling with algae and this has fixed my tank!!
