Tricky to find in the shops
I use these in place of the more common active carbon cartridges in my Fluval U2 aquarium filter.These are much better when there are live plants and at the same time, help control algea by reducing phosphates.They are also excellent for reducing nitrite levels and ensuring good quality clear water.These are really tricky to get in even specialist shops - so the availability on Amazon is appreciated.

Nitrates reduced - Fluval 2 Plus
Bought this to help reduce the Nitrates in my 180l aquarium. I thought they would fit a Fluval 2 Plus but they are a little too big but I managed to snap the plastic frame and then squeezed them in. All working well and even the nitrates have gone down. Not sure if its these cartridges on there own which have reduced the nitrates aSI am also using them at the same time as adding NitrateMinus which I have only used the one. Nitrates were off the scale before and bright red on the test kit chart so well over 160ppm but tfter running the filters for about a week now the nitrates have dropped dramatically to 20ppm which is fantastic.

Works well
My tank can go longer between cleans with this filter. It works much better than I expected and I will be buying it again when they need replacement. I would recommend it to anyone
