Fluval Carbon Filter Media for Aquariums, Premium Bituminous Carbon Inserts, 100-gram Nylon Bags, 3-Pack, A1440

The water in my tank is crystal clear so must be doing a good job.

Le doy 5 estrellas a este producto ya que cumple con las espectativas ademas del precio y la presentacion, costa de 3 bolsas individuales con una malla fina de 100 g cada una, el carbon activo es de buena calidad.

Great item thank you

Fits perfect in my 307 model.

Ottima qualità, indispensabile per il mio acquario

Definite helps to reduce odors in my turtles aquarium and keep the water clear...If you are having trouble keeping the water clear, try to block away direct sunlight from hitting your tank with curtains or a hoodie and make frequent 50 percent water changes to prevent algae blooms.

Funktioniert auch gut als Filtergranulat für Wasserpfeifen. Etwas feinkörniger als das Originalgranulat, entsprechendes Sieb benutzen.

This gets the job done. It takes a day or two for you to realize the change but it works like a champ.

As expected

Alles prima mit diesem Produkt macht was es soll und für den Preis völlig O.k. würde ich wieder kaufen Danke.
