Why is Live Rock needed?Provides the necessary
jumpstartMedium for nitrifying
bacteriaDenitrifying bacteriaGreat biological filter Huge amount of surface
area/ very porousMade of calcareous
skeletons

Harvest by hand Damages pre-existing reef structureHammer to break off chunks of rockBanned in Florida Other countries starting to shift towards
aquaculture

AquacultureSuspended in water column by raftsLet sit on bottomRock is left up to 5 years before harvestAllows time for colonies of growthOnly maintenance is picking off unwanted
algaeSpecial seeding facilities – Walt Smith Fiji

It’s not ready yetStill have to remove dead matter
from transportContainer to completely cover rockSaltwater, thermometer at 76
degrees, powerheadScrub all dead matter off rock and
let it cure Frequent siphoning/water changesCould take a few days to a monthWhen water stops smelling you
can put into aquarium
Curing
