Hi, I am about to add sand to my new tank and was was going to run a fluval 206 external filter. I was just searching the net for sand and came a across a sand sump/filter. Can someone explain what these do and how they are used as there does not seem to be any instruction information that I can find online. I understand the filtration part it's the sump part I am bit confused about as this sits in the tank.
