When selecting live rock....Cured pieces are best. That means that they have already had all the organic matter that died off during the transit and selection process well...die off and gorw beneficial bacteria. Also...Look for porous pieces. Heavy, dense pieces don't have as much space for bacteria to colonize, and should be avoided. Also, pieces with big holes allow for your various wards to inhabit and hide (important for some species). Anyways...I like to find some that have good coralline algae growth if possible. This is sometimes purple, pink or green. It encrusts the rock. Having some of this present makes it easier to later grow more on the rocks, and it will look spectacular. Most LR
available comes from Fiji. It's, for the most part, pretty good rock. It's what I have in my tanks, and I have many beneficial hitchhikers that came in on those rocks. (Some, not so good, lol) It costs around $4.99/lb. in my neck of the woods. You can order from Fostersmith.com boxes of it for cheaper. Also, a LFS
in my area sells rock from the MArshall Islands for around $14.99/lb. Too rich for my blood, but it does have some good algaes and coral colonies attached to it.
If you're stocking a large tank, you can use dead LR
, or base rock, on the bottom and LR
on the top to save money....just takes a bit longer for the proper colonization of bacteria and such.
