hi all i have a fluval 2 filter ,can anyone tell me ,when opened up it has 2 sides for the filter sponge, i was wondering reading posts about wool, does this filter not use wool,i bought the whole setup second hand, so dont know what the make up is,although it certanly cleans the water well thanks

Is this the Fluval U2? If so, no, it doesn't use floss or wool. However, I've got the U3 and removed the carbon sponge and replaced it with floss. There's no real reason to use the 'proper' Fluval media; as long as it doesn't impede the flow you can put whatever you like in there
