boxtech Aquarium Bio-Sponge Filter Sponge (BT306 Replacement Sponge) - 3 PCS

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.

This little filter is perfect for my small tank. I wanted something that would do the job, but not take up too much room. Works a treat. Water is crystal clear.would highly recommend.

For our small tank with just a couple of fish in this is a very good fit.It's easy to clean and use and look good as well.

Came broken

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

Come with nothing completely useless to me,

Works perfect in my reptile paladarium 😊

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

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
