I have a 65 gallon tank which I'm attempting to turn into a successful saltwater tank. I've gotten the specific gravity right around 1.023 and have been running the pump for a couple of weeks now. I'm looking to buy some live rock. I ran across this site: www.oceanproaquatics.com. Just wondering if anyone has any experience with this online store? I'd like to buy 45 lbs of the fiji base rock and then 45 pounds of fiji premium live rock. I don't get it...what is base rock exactly? I doesn't look very "live" to me. Any advice on this matter would be greatly appreciated as I am new to saltwater aquariums. THANKS!
