Average filter needs frequent cleaning. It's not terrible, but whatever aquarium you have, get a filter for a larger one

I use it for a 45l aquarium, it is very powerful, the water is always crystal clear. It makes no noise at all.

Awesome filter, sturdy construction with many placement options, suction cups that don't come off with the slightest touch and the water... crystal clear. Great value for money

Beast, I have it here for 2.5 years and it's wonderful. I have loaded it with a sponge wrapped in cotton filter and organic material sera siporax mini. I have it in a 60-liter aquarium with 2 goldfish, 2 algae scrapers, and 5 natural plants, and the water is crystal clear. Also, if you want additional cartridges/chambers in the filter, you can buy them separately and add as many as you want to this one and to its larger version, the Serafil 120
