Fluval U Interne Filters Schoon en Duidelijk Cartridge, Wit

I was struggling with the water clarity in my 200l aquarium which has been up and running for over a year now. Even when everything had settled days after partial water changes, vacuuming the sand etc; the water still didn't look great. (I do only change the filter media when absolutely necessary and normally give it a wash in the old tank water.)I spotted these cartridges on Amazon and thought i'd give it a go; not really expecting much. I put one of these into the Fluval U4 filter and within 2 days the water was clear! I think they're fairly priced and definitely worth a go!

Achat de la marque Fluval suite à un aquarium de la même marque. Changement depuis peu de l'aquarium de la marque Fluval pour un Aquatlantis, les produits de la marque Fluval restent cependant aussi bien mais la forme n'est pas adaptée pour l'aquatlantis.

Awesome product, I find it doesn’t last 4 weeks but I use it in a turtle tank not a fish tank so that’s probably why! I would buy plenty more if you had more sales on them, full price is abit too expensive when for me they don’t last the 4 weeks!

Dachte erst es wäre teuer für über 20€ ein 2er Pack ABER es sind 4 Stück für den Preis. Das ist echt ok. Passen perfekt in den passenden Filter. Hab keinen Unterschied zu normalen filtermedien festgestellt. Ich fülle lieber mit siporax weiterhin. Da es sparsamer auf Dauer ist. Siporax lässt sich gut auswaschen.
