If you have a massive amount of live rock there's a very good chance adding more surface area is not the answer. Seeding the bricks is not necessary IMO.So, I have a relatively new 120, heavily stocked and with a massive amount of live rock, with some very large pieces. I put a Brightwell Xport N03 dimpled brick in my sump, at the bottom, at the end of February. I did NOT seed the brick and I have not seen any positive results re nitrate reduction. I would think that 12 weeks or so, would have been sufficient time to cultivate nitrate gobbling bacteria but that has not been the case.
It is a different animal than the Marinepure-I believe better- and find it baffling that it has not worked yet; perhaps it needs more time? Am tempted to get another brick and this time, seed it.
