The substrate connoisseurs are back with a brand new product. CaribeSea recently announced their Life Rock, an an aragonite based live rock substitute that is infused with live bacteria and made to look like the coralline laden live rock that you often find well-established aquaria. And because the rock product contains no cement or decaying material, it requires no curing prior to use. The CaribSea Life Rock will come in 20 pound and 40 pound boxes, though retail pricing details have yet to be released. The rock is currently available, at least at the distributor level, and we expect it to start trickling out to hobbyists in no time. MORE: Bacteria Infused Life Rock on the Way from CaribSea
