About This Item

Details

  • Crafted to make taking care of your finned friends easier for you.
  • Design is made for neon tetra, betta, fry and other small fish.
  • Produces little bubbles, which help form a current, add to oxygen levels, and encourage breeding and spawning—and the sponge filter is perfect for providing extra food.
  • Just connect an air pump and airline tubing (sold separately) to the filter and put it in your tank!
  • If it gets dirty, simply use water from your tank to clean this filter and rinse until the water is clear.

Love this tiny filter!!

I currently have a 3.5 gallon tank with 1 dwarf octo cat and my betta. I needed a small filter that wouldn’t agitate the water too much. I had one before and since

I currently have a 3.5 gallon tank with 1 dwarf octo cat and my betta. I needed a small filter that wouldn’t agitate the water too much. I had one before and since mine is showing lots of wear and tear, ordered another. My two “boys” are quite happy and content with this new filter. It also adds the oxygen to the water that is greatly needed. Thanks Chewy for helping keep my fish happy and healthy!

Safe for Bettas and shrimp

I bought one of these for each of my 5 gal aquariums. They are for my betta fish and red cherry shrimp. I have both of the sponge filters hooked up to one air pump

I bought one of these for each of my 5 gal aquariums. They are for my betta fish and red cherry shrimp. I have both of the sponge filters hooked up to one air pump although it's a little tricky to get the air flow correct for each tank when using a single air pump. Sponge filters are unlikely to cause any damage to Betta fins or to cherry shrimp and help maintain the nitrogen cycle. They are super simple to use and don't require replacement cartridges so they're economical as well. They seem to be well made and durable.

Perfect product

The product is exactly as shown in picture! Size is perfect for my 2.5 gal tank. I would recommend. Requires tube to be attached to base but is simple to attach

water filter works great for small tanks

It is doing its job, and I have just washed or rinsed out the sponge every so often, so far so good

Love the sturdy base

Base is for sure heavy! I don't think I can figure out how to put airstone within this sponge filter. Quality is pretty good for the most part!

Tank filter

The fish love the bubbles but it doesn't clean the water as much as I thought it would and I only have it in a one gallon tank

Works well as a filter

Works well if you can only get it to sink. Wants to float.
