DIY fliter idea for the penguin 330.

thanks J.Schmidt I'll give that a try...

I just got a 6 pack in the mail from big al's ($8.99), so it looks like I'll have a while before I try it though

Filterfloss is one of the greaest cheapest things to use in your tanks. Tons of surface area and lasts forever.

I just cut the worn blue pads off and rubberband a piece of filter floss to the cartridge back- use and toss! I do this in my high waste goldfish tank so it is easy to change the floss really often.
