Substrate for my 240 build

[Rob Top1]

Each day I am getting a step closer to having my 240 back up and running. This will be SPS dominant and as such high flow. Two Reeflo Barracudas, one as the return the other on a closed loop with an OM 4 way. Not sure about circulation pumps as I am looking at about 14,000 gph accounting for head pressure. So what's on the bottom of your high flow tank? The system will have a 120 remote DSB as well as a sump that holds 75g and a 65g frag tank.
Been thinking about a thin layer of CaribSea Super Reef Floor. Its a chunky substrate with shells and 1-4mm size pieces of sand/crushed coral.

That is a good choice.

Thanks, looks like I'll continue as planned

I liked sand at first, but it just became a storage area for nitrates and phosphates. If I started over, I'd do bare bottom.
