there's my build thread.I think the second or third page I began my foam wall build. I LOVE IT!! super mega bio sponge of filtration!
I will do a foam wall in every tank from now on. Even if Its just going to be in the sump, I cant praise them enough! They have all the same properties as base rock, so except they seed extremely fast. Within 6 months you will have a living wall!
