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.

These are so hard to get in the shops as they never have any!! So ordered a load of them on here and they were cheaper! I have planted tanks so these are a must as the original carbon cartridges remove the plant ferts. They also last longer than the carbon cartridges which is another bonus!

I had loads of algae as my tank is quite close to high amounts of natural light. These filters have made the world of difference and the water is much clearer with less algae growing on the decorative pieces.

These cartridge filters have very very little activated charcoal in them. And because they are so flexible they allow water round the edges after being cleaned/removed a couple times. The newer model of these works alot better.

I was advised to use these filter cartridges as I was struggling to grow plants. Carbon filter cartridges remove any plant nutrients you may put into the tank. I find that now my plants are growing much better and the quality of my water is more stable, as these filters remove nitrates and nitrites, which can harm ground feeders like Corys. I now only need to use carbon if there are chemicals I need to remove from the water. A wonderful Fluval product, but then I once read that Fluval make the Rolls Royce of aquarium products. I would have to agree.

I can't really praise these, they do the job but are very boring.

I'm dosing my tank with liquid CO2 and plant fertz, so didn't want the carbon filters taking the chemicals out the water. Have to assume these work. Simple direct replacement fit into the U2
