🐟 [HITOP 2 Pack 2.5in Mini Sponge Filter for 1-15Gal] This Aquarium sponge filter should be used together with an air pump and cannot be used alone. (The air pump isn’t included and should be bought separately.) And it adopts round sponge to increase the surface of filtration that is good to filtering efficiency. The dense sponge can effectively absorb impurities, bacteria, feces and debris in the aquarium, keeping the fish tank crystal clear.
🐟 [Easy to use] Come with 2 pack Diameter 2.5in round sponge filter and 3.2ft air tube, very mini in size, can be well hidden behind the decorations. Put the sponge in the tank and press it several times to fully absorb tank water to make it sink to the bottom. With a weighted base, the filter will not float on the water surface.
🐟 [Filtration and oxygenation] When the air pump provides air to the fish tank, the air passes through the filter, causing a difference in air pressure, and the water flows from the side with high pressure to the side with low pressure to achieve the filtering and oxygenation effect. Air pump is not included.
🐟 [Ultra-Quiet & Energy-saving] Powered by air, this aquarium filter works silently and have no impact with your lovely fish and human life, safer for young fish. Air pump and this sponge filter share the same power source, more power saving.
🐟 [Application] With simple but unique design, this internal submersible filter can be used in both salt water and freshwater. Suitable for tank up to 15gallon. Excellent for small size fish like betta, dwarf cichlid, guppy, killifish etc., shrimp, breeding.
Customers say
Customers find the aquarium filter works well for keeping 10-gallon tanks clean and appreciate its compact size, with one mentioning it fits perfectly in a 5-gallon Aqueon tank. They describe it as relatively quiet, good value for money, and praise its quality. The filter’s weight receives mixed feedback – while some say the weighted base is heavy enough, others report issues with it floating up in the tank.

Working great
Needed oxygenation for my 75 gallon tank. i ordered the product along with the sinking sponge filter things 🙂 Comes with 2. i am only using one at this time as it suits my needs completely. Relatively quiet and plenty of power that can be turned down. sinks to bottom and looks nice n the tank compared to most i have seen. seems to being my fish to life with the added oxygen in the water :”-)

Perfect for little tanks and has an air stone
These are perfect little filters for small (2-4 gallons) nano tanks!Happily it comes with a tiny air stone built in for fine bubbles.It fits into the aquarium in a compact way, and is super quiet.Will by these again.

Works well!
Good investment and works well at keeping the 10 gallon tank clean and oxygenated. It’s been in use for a little over a month now. We have guppies, mollies, a pleco, snail, catfish and they all seem to be happy. This sponge filter replaced a tetra carbon filter that was bulky and you had to keep purchasing the replacement filters for it. So we consider this sponge filter set up as a win win. It’s easy to clean and reuse, works great in the tank, has a dual purpose, doesn’t take up that much space and comes as a pack of two! A good tank solution for filtration and air.

FANTASTIC PRODUCT
This is a Great Buy. You get a filter and bubbler all in one piece. I don’t know how the smaller one is…but I bought the larger one for my 3 gallon cherry shrimp tank and with the tiny stone black gravel and a couple of real plants….It looks WONDERFUL, absolutely no noise and works GREAT!

No flow
This is in a small tank and should be all I need, but doesn’t actually move any water through the filter and out the top. The sponge ends up full of stuff but it doesn’t contribute to flow at all.

Works well.
I like that it comes with air stones, and I didn’t need to customize it to get an air stone to fit. This works as any sponge filter should. It has a round sponge design, which is unique. It is semi course, not quite as course as Aquarium Co-op, but more so than many in this price range. The supplied air stone is the normal 1″ style. You could run a higher quality stone, if you have a big pump to really get the air moving.All the negative reviews are strange. Seems people expect a sponge filter to come with a pump??? This thing is like eight bucks, lol.The base is weighted and will sink once you saturate the sponge. It comes with a short length of air hose. I prefer silicone, so I didn’t use it.I have the 40 gallon rated sponge in a 29 gallon tank with 2 Penquin 200 hobs running. I also have 2 of the larger sponges in my 55 gallon with 2 Penquin 350s. I have one each of the smaller sponges in my 10 and 20 gallon tanks with Aquaclear hobs. If you are running this as your sole filtration, I would go double, at a minimum, if you’re running it in tandem with an hob, running to size should be fine. (I would literally run 2 of the 40 gallon rated sponges in a 20 gallon as stand alone filtration).

Cute and chic but floats…good with gravel though
It is so cute and a very chic peice. The only problem is that it floats and my arrangement is on a filter pad instead of gravel. I think it would work great pushed into some gravel or rocks. Sad to have to return it. Also, provides a soft column of bubbles but too narrow for my specific purpose. I need a tornado. Very sleek though.

Great sponge filters!
My new favorite sponge filter! These are well made and do have the air stone in it so the bubbles aren’t big and disruptive. I bought the small size, one is perfect for my little 5 gallon.
