Just a quick question on my internal juwel filter i am changing the black carbon sponge to the blue course sponge, the blue sponge is over double the thickness of the carbon do i need to cut it down to the same size or could i just put it in there?
It would go in fine as with all the media in there does not reach the top of the cage type thing that holds it all together but thought there maybe a reason for it?
thanks
