I'm the type of guy that like the look of minimal rock in my DT. As far as having more surface area for bacteria to grow on do people still use Marine Pure blocks or spheres in their sump anymore or is there a new technique that people are doing?

I added them because I don't have a lot of rock in my 5g pico but I might have enough rock and the spheres are just extra. I'm curious about Randy's take on corals and ammonia. Maybe I should let my corals do the processing.
