Forgive me if this is a dumb question, but do the MarinePure blocks take the place of live rock in the filtration cycle? If so, should I add a 8x8x4 block to sump and buy a few less pounds of dry rock?
My tank is a 40B with 20T sump and I had planned on using 40lbs of dry rock, 20lbs of live sand, and 1 MarinePure block in sump.
