Sponge Filter
How Does It Work?
Sponge filter uses bubbles of air from an external air pump, or an integral water pump to draw water through the sponge.
What Maintenance Does It Require?
The sponge need to be rinsed about every 2 to 4 weeks. It’s helpful to wash the sponge gently with water from the fish tank instead of tap water.
It is good to replace the sponge after 3 to 6 months’ usage as the holes of sponge is gradually clogged by the tiny debris.

I'm using this in a nano tank. It's only been up and running for a week, but it seems to be doing what it's supposed to so far.

Excellent filters! Washable. These should last a typical hobbyist about 2-3 years. Love these

I’ve been using these small sponge filters that connect to an air pump line for months, and they are just as effective as the more expensive hang-on-back (HOB) filters that pump water. These simple yet highly efficient filters provide excellent biological and mechanical filtration while maintaining gentle water flow—perfect for fish, shrimp, and fry tanks.One of the biggest advantages is their ease of maintenance. Every couple of weeks, I simply dip the sponge in dechlorinated water and squeeze it a few times to rinse out the sediment. It’s important to use chlorine-free water to avoid killing the beneficial bacteria that help keep the tank healthy.Compared to traditional HOB filters, sponge filters are **cost-effective, quiet, and reliable**. They don’t require expensive replacement cartridges, and they run smoothly as long as the air pump is functioning. They also provide great aeration, which is a bonus for oxygen-loving fish.Overall, I highly recommend these small sponge filters for **any freshwater aquarium**. Whether you’re a beginner or an experienced aquarist, they’re an affordable, low-maintenance, and highly effective alternative to pricier filtration systems.

I always preferred to use sponge filters for 2 reasons, they are cost effective filters that can be ergonomic for every fish tank, and that they help oxygenate the tank. Even the whole setup is affordable since you can buy airpumps for 6 dollars rather than getting a whole filter that has disposable catridges for more. They are especially a great deal since 3 are around 5 dollars and are great quality. Overall I recommend this brand to get the most bang for your buck.

First, it is a good idea to mod these to use an internal air stone. Use snips of some kind (like small side-cutters) to cut space on the inside, then attach a small air stone (0.6" cylinder worked for my "small" sized filter) inside the filter from the cap using the tubing. Doing this will make the filter create finer bubbles, providing better filtration and less water surface disturbance. It will also quiet the bubbling from the filters down quite a bit.Sponge filters are great all-round filters, and work well for fish that don't like movement (like Bettas). You need an air pump and airline tubing to use them, though. They won't flood the ground around the tank like other types of filters, and they don't really break (air pumps do, though). They are a little unsightly and harder to hide than some hang-on-back filters, but not impossible.This particular sponge filter is about as good as any other, with some caveats. Some aquarium experts recommend larger, open-cell sponges for their filters, which will clog up less than the fine closed-cell sponge on this filter. Because of this design, you will need to clean this filter more often than you otherwise might need to. It does work, though.Also, this filter is not quite weighted as much as it should be. Even when fully soaked, it's a little too buoyant. A good sponge filter should sit comfortably on the bottom of the tank.Do not ever replace the sponge, by the way. To clean it, you pull it out of the tank and squeeze it out gently in the old tank water during a water change. The sponge may last years, and will harbor beneficial bacteria for your tank. If you replace it, you will mess your tank up. To replace a filter with another, you want to run the old one alongside the new one for a least a few weeks to help the bacteria colonize the new one.
