boxtech Mini Aquarium Sponge Filter，Internal Fish Tank Filter for 5-20L Fish Tank (No Include Pump and Tube)

I bought this filter with the matching air pump. I am very pleased with its performance and the sponge within the filter is visible and very effective.Together with the air pump my fish are very happy and lively.

Works perfect in my reptile paladarium 😊

There is nothing not to like about it

Came broken

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

Come with nothing completely useless to me,

Bought this for my spare tank for breeding or sick fish as I couldn't find a filter small enough that worked well, this is perfect

Great little filter , easy to set up, works well, seems very powerful.

Works well

The media could not be loaded.  Sehr gut für kleine Gläser 👍👍👍

Filtre bien

facile da montare e pulire

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
