  • Nice set of three tiny sponge filters good for up to 10 gallons.
Pattern Name: Up to 10Gal
I got the pack of 3, which includes 3 filters. However, I noticed in one of the reviews that theirs came with tubing for them and an air adjuster piece. I did not receive any of that. I just got the sponges and small parts for the filter itself. With that said I really like them so far. I have recently gone to these types of in-tank sponge filters for some of my tanks, and I like them. I use them in addition to the main filter, though. I was so happy to see that someone made extra small ones like these because everything I saw up to this point was just too big for my beta tank. The tank itself is 5 gallons, but I have a divider in the middle right now so it is housing two beta fish. The filter is on one side and cant clean on the other side of the divider. And it is a bad filter anyway. It sits up too high with hardly any water flow through it. I want to take it out and replace it with two of these. One on each side of the divider. And because they are so small, I can do this without worrying about the filter taking up too much swimming room from my betta fish. They aresSuper easy to set up. And I appreciate the bottom having weight to help it stay down. All you need, and you definitely are going to need this, is an air pump. In my case, I need either two of them or a splitter. (I forgot what they are called) I do wish that the air tubing didn't go down the same spot the air bubbles come up from. Fo a more pleasant look. But I'll get over it. ... show more

  • Work great and good value
Pattern Name: Up to 10Gal
Love these little filters! They're perfect for my 5 gallon quarantine tank. I modify them to add an air stone so I get more bang for the buck (there are youtube videos on this if you are interested). They are not weighted, but they sink just fine after squeezing the sponge in tank water a time or two. Easy to clean - just removed the cap with the tube and air hose, pull off the sponge, and squeeze it a few times in your dirty tank water when you're doing a water change. Your beneficial bacteria is housed in the filter, so never rinse it in chlorinated tap water that can kill it off and mess up your cycle. Sponge filters are so much quieter than hang-on-back filters, too. Once you go with a sponge filter you will never go back! Very happy with these filters. Also, it's always great to have some back ups in case you need them so getting 3 is a nice insurance policy for very little investment. ... show more

  • Good. Go an extra size up if it fits.
Pattern Name: Up to 10Gal
I love that these are weighted on the bottom. I have gotten some sponge filters that literally float up. I have not had problems with them clogging... Yet... I have had the problem where they don't quite provide enough filtration for the setup where they are installed. I have been a long time advocate for over filtration, and I am reaffirming my belief with this product. I have bought them for both primary and supplemental filtration. I've found them falling short in both categories. So, if you have a canister or hang on the back that tends to clog, you still want to go a size greater, so that you have enough supplemental filtration until you notice that the primary filtration is clogged. Yes, I am a lazy (OLD!) fish keeper, and I am not ashamed. That said, I believe in contingencies to make sure that my fish are healthy despite my own limitations. ... show more

  • Quiet and compact
Pattern Name: Up to 10Gal
Exactly as it needed to be! Great little filter for my 10 gallon tank. 3 for this price is awesome because you can tear one apart trying to put an air stone (sold seperately) inside it thats too big and have 2 extras. (My fault.)

  • Excellent little sponge filters for all my house plant only filtered tanks.
Pattern Name: Up to 10Gal
All my tanks are house plant filtered, so these little sponge filters are great for my neocaridina shrimp tanks in absorbing the occasion debris. I also have two of these in my 55 gallon aquarium. Small for the tank size, I know, but as my house plans do an excellent job of keeping the water crystal clear, these sponge filters are basically for the sand silt my cory’s and kuhli loaches kick up. Once I see debris on the outside of the sponge, I simply disconnect from the tubing and run them under clean water, squeezing the sponge to remove the dirt and debris. They come apart easily, so you can also slip the sponge off that way to get a better clean. There is no issue with removing biofilm as I replenish my tanks with Bacter AE as needed. Other reviews spoke of the filter floating away. Ridiculous. Obviously you need to squeeze the sponge inside the tank or sink to replace the air in the sponge with water. No need to weigh these down once you do this. They sink right to the bottom when full of water. Other reviews spoke of the bubbles being too loud. That’s not the sponge filter, that’s the pump you’re using. I personally use an adjustable pump as my shrimp like to eat the biofilm off the sponge and I don’t like the bubbles being too rough for them. I would like to see decent replacement sponges for these filters, however. The ones available don’t have great reviews. ... show more

  • Way better than Cartridges!
Pattern Name: Up to 10Gal
I absolutely recommend these filters it works really well . I used to have an old school filter where you have to changed out the cartridges but I researched it and saw several videos on how the sponge ones are more beneficial. My betta has a lot more room to swim now and it’s pretty quiet . And just a tip for those who are saying that it floats it’s because there are still bubbles in the sponge you need to squeeze it a few times while it’s in the tank and it will stay down. Hope this helps. :) ... show more
