You should try to get your live rock online. The prices are much better. As for using it to cycle your tank...I have never seen one be able to be done well by LR
. Just walk into your grocery store and ask for uncooked shrimp, sometimes they will straight up give you one if you tell them you only need one. I ordered my LR
from saltwaterfish.com before I cycled. The prices couldn't be beat, but that was in November so there might be a better deal out there currently. Still a great place to start. Keep us posted on your progression.
