Was hoping to get some recommendations on what to use for prefilter material in the sump. It will be the first thing the water passes through as it enters the sump. I would like something that is easy to clean/replace... any ideas? I don't want to use a sponge b/c it will slow down my water flow too much and possibly cause overflow. Any other suggestions? Thanks guys.
