Sugar Sand, Aragamax Select, Or Larger?

[blacknife]

I like the look of sand, the owner of my last tank had 1" + Crushed coral in there without any problem but after I dumped some sugarfine in it started getting the stank spots. I think I might try a bag of seafloor grade in this setup before I upgrade to whatever my next setup is.

This tank started out with some sugar fine but with some of the flow i ended up with bare spots. I have sucked out most of the sugar fine leaving a shallow sand area over 1/3 - half the tank and a rubble zone in the other half. ZnP are in the rubble zone and I pull an occasional natural spreading frag out of there.

I tried bare bottom in my frag tank and the bottom cracked.. although i do not believe the crack was related to the bare bottom, there was no rock-slide that i could see i just came downstairs and the tank was cracked.
