Suggestions wanted on sump filter
I am beginning to get parts together to build a sump/fuge. I have looked at a lot of pictures online and noticed there are a lot of ways to filter the overflow into the sump. I know filter socks are very popular. I also have noticed many people do not use a filter at all. My current setup runs out on a piece of eggcrate that has filter material laying on top. Please weigh in with your opinions as to if a filter is needed at all and if so what type and why.
