New guy, Rock and sand questions

[banditpowdercoat]

OK, First off, Hi all, new here from 100 Mile House BC. Have had freshwater aquaria for 7-8 years now, and am finally venturing into Salt. Just got a 190L corner unit Aquarium, Fluval brand, with a Fluval 205 canister filter. I will get a sump eventually, when time and tank requires it. The problem is my LFS does not have Salt supplies in stock. No rock, sand or fish. But, they can order in anythign I want, and it comes in pretty quick, 3 days. My question is, what should I be telling them to order for me? I will be eventually gettign a pair or Percula Clowns, and the rest, well, havnt gtoen that far yet LOL. Pretty much the norm, huh, Wanting to get into salt with Percula's. But Daughter has told me how it is going to be HAHAHA. Also, waiting longer to get tank to cycle is not a problem so if I could use more base rock, or just regular aragonite instead of live sand, that would be ok. I am gettign overwhelmed with the different choices there is out there, Aragonite, crushjed coral, types of live rock, etc. Would like a little 'push' in the right direction for product/brand selection.

Ohh ya, I would liek a healthy cleanup crew too, Hermits and the like. I think the cleanup crews are just the coolest thing, watching them work away..
