macrorocks vs caribsea dry sand and more

so im just doing the normal 2 inch sand bed and i was curious what MM you guys prefer i know i want somewhat course sand since ill have high flow and i dont want it dusting everywhere

is the caribsea dry sand a good choice? also if liverock is dying (the part thats submerged in sand what would that indicate?

and how many nassarius do you think it would take to turn over the sand properly in a 180 gallon system

 

I'd get reefrocks.net, they sell free sand with a rock purchase. Its prerinsed which is AWESOME. marcorocks is ok, but really dusty and blows around. Caribsea is nice though.

And check out reefcleaners.com they have suggestions for snails for your tank

 

yeah i emailed john? i think from there im just being an impatient child tonight so much planning to do
