I net mine as well, but as said the majority of the gnk is imbedded.
I used to cut foam Blocks for my emporer and then cut a hole in the block large enough to accomodate the oddball intake tube. It worked almost too well with the emp. The faom had a tendancy to plug up with that filter. But honestly an Emporer seems to pick up more dirt than anything alse rated similarly. I always had more gunk in my Emp 400 than I did in my AC 500. But both are great filters in the land of Hob's (IMO)

i know the topic is prefilters for aquaclears but does anybody use a prefilter on your penguins? i have a penguin 300 and the intake is a big odd shape.
