Hello all. So I went ahead and ordered a waterbox infinia frag 175.6 and I am trying to plan out my setup. I have decided to transfer rock from my current setup to avoid starting from scratch. However, I plan on having nothing but pvc and egg crate as the “aquascape” so the rock will go in the sump? That seems like a lot of rock will be needed and will take up way too much space in the sump to allow for equipment. Any other ideas?
