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
