Review: I swear by these cartridges! - 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 desertcart 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!
