Since this is just starting up, I would highly suggest against premium live rock. I would buy the cheapest live rock possible since you will want to have some of the die off start your cycle. Premium cured rock costs several times as much anyways. Unless you have a lot of money, and can buy cured rock IN TOWN and keep it SUBMERGED the entire time, cheapo live rock (uncured stuff) will be the best. Shipping cured rock turns it into UNCURED rock just like that...Give the uncured rock a decent scrub and its now the same as the cured rock that was shipped. Id get 15lbs of uncured rock and later get some dry base rock (even cheaper) that will become live with time.
Id really reccomend getting some sort of RO
is better) system to give yourself a great headstart against algae!
Dont buy any live sand, get dry aragonite sand and youll save alot of money and time spent cussing about the nasty stuff from the sand that will seem to forever plague you.
