Filter cups

[sacora]

Hey reefers, anyone have any experience with pro clear filter cups?

I don't know the brand in my 100 g fish tank but I don't bother rinsing or dumping them, which is much better than socks.

Not familiar with the brand either, but I use these in my sump with 4" filter cup holes.
