Thats another one I ran across but I still cant find the information that steered me away from scrubbies and to Poret foam. With a sump the size he is making I am not sure he can make the wrong decision. One of the benefits to Poret foam is that every 6mo or so, you remove it and do a quick clean by rinsing it out with tank water or banging it on the sidewalk and put it back in. No fuss no muss!
