boxtech Aquarium Biochemical Sponge Filter with Air Stone Ultra-Thin Round Air Driven Clearable Bio Quiet Filter Sponge for Shrimp Nano Fish Tank (Not Include Air Pump and Tube）

There was no mention that the air pump is not included. It is disappointing to not being able to operate the apparatus

Funziona in un piccolo acquario. Bisogna pulirlo spesso

Nice and quiet product. I was expected something a little bit smaller, but it's makeing a good job. Water is clean, fish is happy and filter looks okay.

This works well- I bought 2 and cleaned the tank up fast, it’s a small tank and a good option when you have a small take and don’t want a big filter

This little filter has saved the day, i have a new aquarium set up, and used all the tap safe and filter aid products and let the filter run for 2 days before getting the fish, after 2 days my water was going milky, the soultions i added were just creating a milky film and not being mixed by the filter, infact i very much doubt the new filter was working at all. I got this to assist my existing filter, it arrived today just intime, as i couldnt see through my tank as you can see in the 1st picture, i instantly set the filter up, it took less than 1 min to attach it to my air pump and plonk it in the tank -pic 2, to my utter amazement, 5 hours later my water is almost crystal clear -pic 3, and the fish are now swimming about and playing happily in crystal clear water. I have purchased a 2nd one and will be binning the crappy filer that came with the tank, 100% reccomend

Ne fait pas de bruit et filtre bien en faisant de jolies bulles
