U live in Florida, u can get it for free.
please refrain from advising people to do things that are against the law.
many people may not realize it, but collecting live rock in florida is prohibited.
as for the live rock / cycle time question. it is not a question of time but rather a matter of the condition of the rock.
live rock is either cured or uncured.
uncured means that some organisms have died off in transit. uncured rock will have a smell to it that is either fishy or like the beach at low tide. this rock will release decaying material into your water resulting in an amonia spike. many people use this spike to start the nitrogen cycle (as aposed to damsels, cocktail shrimp, urine, or expensive additives).
cured rock has had time to clense itself from the decaying material and possibly begin some new growth. cured rock will have no smell and it is ready to biologicaly filter your water from the moment you add it to the tank. many people use this for instant cycling. however, to do this you must have a sufficient amount of rock and a resist adding a million fish the first day.
my prefered method (with nanos) is to use cured liverock (enough for a good aquascape) on a thin (1/2"- 1" ) sandbed.
i add light and coral frags on the first day. i can do this for two reasons. (1) the rock is cured and ready to filter organics. (2) corals add almost no bioload to the tank. if the tank is 5.5g or more i might add a single fish (choose wisely) after the corals have had a chance to settle in. with 10g or more i may add a second fish (use your judgment and track your paramaters)
i have used this method on all four of my nanos ranging from 2.5g to 20g. and i think my pics speak for themselves. [ side note: i do use a refugium on my 20g].
it is particularly interesting to watch all the life that emerges from the rock in my 2.5g because there are no fish to eat the tiny creatures. i have mysis shrimp, every sort of pod, and baby snails. i can stare at this tank for ever.
sorry for the long post... hope its helpful... have fun... and good luck.
