If you have a penguin filter your in luck instead of buying filter media made for the penguins buy media made fo the aqua-tech brand filters at wal-mart. they fit perfect because aqua-tech is actually a cheap brand from marineland. im not sure if there is any difference at all they both say series 133 on the back of the filter and they are exactly the same size. I think if there is any difference at all it is just a different type of carbon in it. I buy my filters for my penguin 350 and 200 from wal-mart for $10 for 6 filters. I would definetly rather pay that then the normal $16-20. just thought i would let all of you know a little secret.
