For the stock IM 75 ext, the sump is RFS39. I've looked all over forums and gpt and can't get a clear answer. I don't wanna deal with filter socks. Is it possible to easily use a filter mat without modifications? I've seen the red seas are best but id like one that works and is quiet and that can fit in my sump. I dont think red seas will fit. Are there any options for roller mats in this sump? If you have a roller mat can I avoid having a protein skimmer? Thanks guys
