the phase Cured Live rock and online retailers should not be used together.
Live rock that might be cured on the retailers end will experence some degree of dieoff during the shippment process. This is because most retailers will ship the LR
covered only in damp newspapers. This is because its so costly to ship rock in the first place but then to add the weight of the water to keep it submerged would be very significant. Even submerged rock will have some die off unless they put enough heat packs to keep the water temp up to 75-80F during the trip.
With that said I got my last bit of live rock from www.ffexpress.com
I belive they have a special now where you can get 45lbs of LR SHIPPED
also has live rock but they have it priced at $99 BEFORE
shipping. Once you add shipping to it your back up close to Flying Fish's price.
