UPETTOOLS Mini Aquarium Sponge Filter, Small Internal Fish Tank Filter Detachable Submersible Filter with Air Stone Suitable for 5-20 Gallon Tank (Air Pumps and Air Tube not Included)

I used this little filter in my "clinic" tank. I have treated 3 balloon platys in a gal of water and it worked perfectly. It filtered the water and at the same time it produced a good amount of air.I treated my fish by dipping them in Methylene Blue before I dropped them in the clinic tank. The filter got stained but it did not affect performance.One thing to note is that it doesn't come with the pump and air line. You will have to have those separately. It does come with suction cup so you can stick it to the wall and it holds it in place really well.This filter really works and since my platys have now recovered, I'm putting the clinic tank away with the filters until I need it again (knock, knock). It's very reasonably priced and it is very functional. I'm so happy to have this in my clinic tank!

The media could not be loaded. I just installed this filter and aerator combo in my small 2.5 gallon TopFin corner aquarium. The filter that came with it didn’t last more than 3 months. I set this up in just minutes, at first I thought the bubbles were so big and worried the current would they’d swirl my small fish around the tank. NOT SO! As you can see in my video, the fish are no larger than 1 1/2 “ in length, small, one in particular. They was no problem with it pushing them around, so I’m relieved I don’t have to find a way to adjust it. The water turned crystal clear and they were able to eat… …. so this item creates a nice flow in the water but nothing to worry about. I came back 2 hours later, two of the fish were swimming in and out of the bubble stream, playing in it. That sealed the deal for me! They’re happy, and I ordered a second one today for my Betta tank. Planning to use filter floss when it comes time to change the sponge, to see how well it works as an alternative to constantly buying sponges. If any big changes I’ll update this review.. It is also really aesthetically pleasing, and I’m happy that it doesn’t have to be clipped to hang at the top of the tank like an eyesore, as most filters. Praying it holds up well. When it comes time to wash/replace the beads inside, I plan to use either small bio beads or zeolite crystals which are being used as my gravel.. (TIP: YOU CANNOT ADD ANY SALT IN YOUR TANK IF YOU USE ZEOLITE BECAUSE SALT WILL CAUSE THE ZEOLITE TO RELEASE ALL THE NITRATES THEY ABSORBED BACK INTO THE WATER.)(Note: the actual pump, and air hose tubing, you do have to buy separately to attach to this filter/aerator. The pump I bought on Amazon. is small, blue, sits behind the tank, and for small tanks up to 10 gallons.)

I bought this filter for an emergency 5 gallon quarantine tank. All I had to do was connect it to an air hose. It didn’t float, but it did sit crooked, so I put a suction cup on the air hose and attached it to the tank wall. I’ve only been using it for about 2 weeks, but overall it seems to be doing the job. (As you can see in the picture, the sponge is no longer white, but has been filtering impurities from the water) The water has stayed very clear, and I like that the air stone in the filter also aerates the water. While I can hear the filter running, it’s very minimal. I haven’t tried to take it apart yet to clean the sponge material, hence I gave it 4 out of 5 stars. Note: this is only the filter itself. You will have to supply the air pump and hose to connect to the filter.

I just got into fishkeeping as a hobby. This filter is placed in my tank where I quarantine small plants it’s pretty quiet and functions. Well, my sponge is starting to get color to it which means it’s working very well built larger than I thought it was gonna be but I’m OK with that. A small amount of bubbles come out so seems like it would be great for sensitive fish. Seems like it's well-made and sturdy. Very easy to assemble comes ready to use and I just put it on the end of my air hose and it seals well. Great filter and I will be buying more for my other fish tanks

This product came with nothing but a box and a filter. The advertising does not say that it has no tube or pump. It is very deceiving. Any other product comes with a pump and the hose ready to go. This is just the filter. What a waste of time and money. NOWHERE does it say that a user needs other parts for this to work. Very poor advertising and I would never have purchased this. My fish now have to wait until I can go to Petco in the morning. I hope they live. DO NOT BUY THIS PRODUCT.

Does not come with a pump.

It has bio balls and an air stone for the same price as other sponge filters. My new go to for nano tanks.

This filter does a good job, the air bubbles come out steadily and at a good flow, this filter realy showed me how bad of a job my other filter was doing. When I upgrade my tank I will definitely get another one of these.
