Aquarium Sponge Filter Fish Tank Foam Filter Quiet Submersible Bio Sponge Filter with 2 Spare Sponges and 1 Bag of Bio Ceramic Media Balls

Would recommend, great build quality, easy to use, and the perfect size for my 10 gallon tank! I thought it really helped keep my tank clean with its bio filter and was the perfect weight and sound level for my office!

Still feels brand new after a year. I cleaned my sponge filters just recently and it’s still holding up. It’s working great with water movement on the surface of my fish tank. Rather it be right at the water line creating a flow or as a mini waterfall. My fish love it. Cleaning is simple. Remove sponge and squeeze in a bucket of mixed clean water and fish tank water. It’s never moved once out of place. Also it’s placed inside a 55gallon tank.

First time using a sponge filter for smaller plant tank. It works well to both filter and circulate the water. Maintenance is easy with the extra sponges, usually swap them out every 2-3 weeks along with weekly water changes. Currently using a 50-100g air pump and it really gets the water moving, the smaller 10-20g air pump also worked just needed more circulation for my set up.

Great filters been using for 3 months with no problems, keeps water clean.

I currently have this in a 29gal heavily planted and lightly stocked. It keeps the water nice and clear. I wish the bubble tube was about 4 inches longer.

I've used a lot of sponge filters in my aquariums over the years, but this is the first one I've actually felt compelled to give a glowing review because it is excellent. The plastic feels strong and just flexible enough to avoid getting brittle and cracking over time, and the ceramic media that is offered with it is excellent quality. I like the fact that the sponges can be run without the ceramic media cup, but I can't imagine why you would want to leave the ceramic out since it just offers more space for beneficial bacteria. The flow through the filter is excellent. I have it running on a tiny usb air pump and that's really all it needs. Since its running on such a small air pump, it is virtually silent other than the sound of the water bubbling a bit. I would recommend this to anyone looking for a low-cost, low-maintenance in-tank filter. I actually think I prefer this over my aquarium co-op sponge filters. I do have one minor complaint, I wish it came in a gray or black color instead of just green. That's an aesthetic issue, though. Not worth docking a star.

I loved it so much about a second one and I’m fixing to buy a third for my other for my last tank. I’m getting rid of the over the back kind and sticking with these sponge filters with the bile balls. They work very well. I recommend 100% and great bang for the buck!

So far would just say stick to a normal filter and bubbler instead of trying this combined one. Did not do much to nitrate and ammonia levels till I gave up and put old style filter back in… does bible a bit. But bigger bubbles so think the smaller bubble bubblers are probably nicer to the fish

Love this product, easy to clean and operate and the fact you have biological filtration too is wonderful. I had to increase the PH and GH in my tank and did it easily by adding some crushed coral in the containers of the biological filtration. Would definitely buy again.
