How large are they? I picked up a spongefilter at my LFS, it was the smallest one they have and it was only $10, that ebay auction was $20 for me with shipping so I just grabbed the one I needed for my fry tank, but it was larger then I expected. Box says its a Seapora 30 and its prob 4-5 inches tall? Not including the tube the airline goes into
That must be American inches.. I am not sure how that converts to British inches..
like we has the ton which is 2000 pounds.. you guys has The British Ton which is a couple hundred kilos.. Don't even axe me how that makes sense..
but then again, conversions were never my strong suit.. I pretty much juss guess anyways..
