Description

Sponge filter uses bubbles of air from an external air pump, or an integral water pump to draw water through the sponge. 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. Great for 40Gal to 60Gal tanks. 4.5 inches in diameter and 8 inches in height. Constructed with detachable parts allows you to easily take it apart for cleaning or replacement. The air chamber produces tiny bubbles which increase the oxygen solubility of water. Air Pump Not Included. Helpful to wash the sponge gently with water from the fish tank instead of tap water.

    • Loved it!

The AQUANEAT Aquarium Bio Sponge Filter Breeding is an excellent choice for anyone raising fry, shrimp, or delicate fish species. Its simple yet highly effective design makes it a dependable staple for both beginners and experienced aquarists. What really makes this sponge filter shine is its gentle filtration. Unlike stronger mechanical filters that can stress or even harm small fish, this unit provides a soft, steady flow that keeps the water clean without creating dangerous currents. That makes it ideal for breeding tanks, quarantine setups, or shrimp colonies. The biological filtration is another standout feature. The sponge provides plenty of surface area for beneficial bacteria to grow, helping maintain stable water parameters and a healthier tank environment over time. Once established, it does a great job of naturally breaking down waste. It’s also incredibly quiet since it runs on an air pump—no motors, no humming—just a subtle stream of bubbles. This makes it perfect for setups where noise needs to be kept to a minimum. Maintenance is refreshingly simple: just rinse the sponge in tank water during routine cleaning, and it’s good to go. The build quality feels durable, and it’s easy to set up right out of the box. Overall, the AQUANEAT Bio Sponge Filter is a reliable, low-maintenance solution that excels in breeding and sensitive tank environments. It’s a must-have for anyone focused on fish health, stability, and gentle filtration. ... show more

    • Low-cost value for a clear tank
Size: Small up to 10Gal
This is a decent little filter. I use it for a 7-gallon planted tank and it more than does the job. I had an algae and bacteria bloom that would not clear after a few months. I bought this filter, filled the chamber it has with filter floss, and put it in the tank. Water improved quickly and was crystal-clear in a couple of days. It’s just a solid two or three pieces of plastic which snap together and are pretty durable for taking apart and cleaning. The sponge on the outside does a good job of keeping small shrimp safe, as usual the enjoy grazing on the filter sponge. For a low-tech setup with a smaller tank, it does a good job. You could probably get away with using this in a bigger tank as well if you’re using primarily to keep the water clean in a low-tech tank. ... show more

I have a 65 gallon tank with a hang on the back filter. I use this sponge filter on the opposite side for more filtration for my fish. It works great and easy to assemble

    • Simple, and effective
Size: M Large up to 50Gal
Installed air stone for smaller bubbles, modified to fit. After 1 hour I could see a difference in the water clarity. Very inexpensive way to add more filtration to your tank. If you have an airstone already, no reason not to put in one of these, you still get the benefit of oxygenating the water, and you gain more filtration. ... show more

    • MUST have in ANY tank but especially for Fry and Shrimps!
Size: Middle up to 20Gal
We were running a Aqueon Shrimp Filter prior to picking this up and what a huge difference it has made! not only do we have no loss of any shrimp, fry or plant but helps keep the tank much cleaner and healthier. I have seen the healthy biofilm develop much faster and easier for the baby shrimp not to mention a happier colony that isn't trying to fight a waterfall or current like salmon anywhere in the tank. Some of them have too much fun with the bubbles haha. Do yourself a favor and ADD AN AIRSTONE! Super easy to search youtube or any search engine, "how to add an air stone to sponge filter" to make your life a lot easier, and more satisfied with the long-term results. It is not hard at all and DON'T FORGET SQUEEZE THE SPONGE underwater in your tank before placement. You want to extract as much of the air pockets as possible so it will sink and stay in place better. Much more appeasing to the eye for your aquascape as well if you have a nice driftwood/rock/plant in front of this, easier to hide compared to other filters as well. Don't be surprised if your fish and shrimp prefer to hang out on the or around it vs in the front of your tank at times :) Replacing all my current HOB filters with this and have not regretted each swap so far. Kick myself in the behind for not making this switch sooner. Super easy to clean just remove the sponge bottom while leaving the air stone and filter running for oxygen. Repeat squeezing out all the air when placing back in tank. Depending on how dirty your tanks get will be how often you need to clean this and I would offset cleaning with your water changes to keep a good biofilm for shrimp and cycled filter to not shock your tank too much. ... show more
