Ok, here is what I ended up ordering:
(5) 40 lb bags of the Ocean Direct Caribbean Live Sand - 200 lbs
(10) 30 lb bags of the Aragamax Sand - 300 lbs
(10) 40 lb bags of the Seaflor Special Grade - 400 lbs
That seems like the best of everything and it should satisfy even the pickiest of substrate dwellers AND give the aquarium pretty good buffering.
In this order, I also ordered (4) 160g IO/RC salt mix and 1 each of the 64 oz bottles of the phytoplankton and microvert food. Shipping for everything was $17.99
I have no idea how they do it but I'm not complaining...
