Aquacity Aquapapa Bio Sponge Filter 20 or 40 Gal Breeding Fry Betta Shrimp Fish Tank Aquarium (Ship from CA USA) (Air Tubing Kit)

This filter is great so far! Even though I pulled out a ruler to get a visual of the size its bigger than I expected, should provide plenty of filtration for my 20 gallon long. The airline hose has a nice tight fit on the filter and after a couple days of running Ive had no issues. The box does have information and instruction in decent English. The item arrived very quickly and was well packaged for travel. I will update this if I notice any issues as Ive only had this sponge filter running for a couple days.

Perfect filter! Bubbles! Planning on getting another soon!

Nice..

These are great for the price! Im very pleased with the performance of the filters

Good size for a ten gallon fish tank. Good product, price & quick delivery.

First of this is a huge sponge filter but it will work well with my axolotls which is all that counts. I didnt expect it to be this big as the one I have that handles a 40 gallon is actually smaller. Design wise love it. Now lets see if the axolotls love it.

I love these filters….no cartridges to replace…just clean and go!

Keeps my 15 gallon pedestal tank crystal clear.

Sponge filters have many uses and can be connected to overhang filters or be a stand alone filter as well. Sponge filters are much easier to clean as well as being able to breed your fish without any problems for the fry or baby shrimps to get sucked into an overhang filter.

Not a bad sponge filter, but if you want to add an air-stone to increase the lift (and filtering power), it requires a lot of modification. Aquarium coop has ones that are air-stone friendly filters that are the same price. Cuts down on the noise from huge bubbles, and dramatically increases the filtration.
