I recently purchased a three-pack of aquarium sponge filters, and I'm impressed with their performance. These filters do exactly what you'd expect from an average sponge filter, and they do it well. The sponge filters efficiently oxygenates the water as well as remove small debris and particles from the aquarium water, contributing to a cleaner and healthier environment for aquatic life. This product comes in a convenient three-pack, providing excellent value for the price. It's perfect for those with multiple aquariums or for spares when needed. Setting up these sponge filters is a breeze. They are userfriendly and don't require any complex assembly, making them suitable for both beginners and experienced aquarium enthusiasts. The sponge filters are well-made and durable. The quality materials used ensure a long lifespan, making them a reliable choice for continuous use. While these sponge filters do their job effectively, they have a simple and standard design. If you're looking for a more aesthetically pleasing option, you might need to explore other decorative filter choices. In summary, if you're in need of reliable, no-frills sponge filters for your aquarium, this three-pack is an excellent choice. It delivers on its promise of efficient filtration, durability, and affordability – everything you'd expect from a solid sponge filter option.

They are "Fine" mesh filters so they trap a lot of small stuff. They are not loud. I have mine connected to a gang valve so I can control the amount of air flowing into it. Easy to assemble, easy to use, easy to clean & they last months & months. My only irritation is that you cannot just put it in a bucket of tank water & squeeze it clean you REALLY have to squeeze it out repeatedly. So I use a small cup instead of a large pail. They really collect a lot of tiny particles so it can be a little difficult to remove it all. But great performance & value.

These work perfect for my guppie/shrimp tank. Motor & filter in one, worth the money.

Good value, great filters, big, doesn't stay in rocks

This filter cleared up my tank in just a few hours. It makes some noise but is quiet for the most part. Will buy again!

Lake mud, fine gravel, and lake water. 1st pic is 2 days settling only, 2nd pic is 2 days with the filter running very low. The spots remaining on the glass are alive or bubbles, bowl is almost crystal clear. Very impressive.

Works amazing! Within minutes I could see debris on filter . Great value and it's well worth the price.

The sponge is very fine which should mean that it would be great for baby fish but outside of that use case I think a coarser sponge would work better. A coarser sponge would be better at grabbing larger particles and would be harder to clog. Outside of the sponge this is a good enough filter.

My Betta was being drawn into the filter and tearing its fins these ones seem more gentle

Very good value for decent quality filters, will purchase again. Also work very well for adding air stones mods. Would recommend.

One of these filters is keeping my planted Betta tank looking nice and clean. It's gentle on fish fins and minimally disturbs the waters surface. Only small complaint is the red part of the filter. That colour sticks outs in a natural environment. Make it black.

I do wish they had options for different types of sponges that could be used, but they do exactly what they say they will!

The foam used for the filters is way too high in density it is well over 30 PPI (PPI= pores per inch).I must clean them at least every 2nd to 3rd day because of the ppi count. they are more for polishing water not to act as a full-time filter. I would not suggest this type of filter to anyone unless they want to use it for water polishing.a lot of the foam filters sold on Amazon are the same, I don't understand why they sell such high-density high PPI-rated foams as a long-term filter. I can not find a decent foam filter with foam density like that of an aquaclear foam rated at 20 PPI except the hygger one with the clay and foam media. I should have got those instead, these filters are only good for polishing water not as a typical filter that is ideal for aquariums. the ideal PPI on foam for aquariums is between 10 to 30 PPI 10 being course 20 medium and 30 fine anything else higher is more for polishing water and short-term use.
