So there are 2 differenct things.
Curing dying off of old organisms and getting the stone clean then cycling building beneficial bacteria living in the rock.
I used the fresh LS
fom the bag no need to cure for that. And then the already cured and LR
from the lfs
. Driven less than an hour home once was in wet newspaper and a couple times with stone in a bag of water.
So due to getting the older rock from the lfs
for a nano tank, and already having it be cleaned, cured and coming with beneficial bacteria, I just put it right in and waited 2-3 weeks to make sure it was BB active and was cycling the fish food I fed the tank every other day.
That is why I said you need to know how long the rock has been in the tank at the lfs
I saw the employees drop in a big box of rock into the near empty end of the rock tanks while I was looking around one day. Then about 40 minutes later someone was buying that same "live rock" not really live rock, from the tubs.
Went to a SW lfs
last week and there was a sign next to the tanks stating that they were not guaranteed Live.
When I started mine, I did have conversations with the specific employee about which stones in the SW
fish tanks were there and for how long and in the big rock cycling tanks which were the ones there the longest and how long. To be sure I was really getting LIVE BB filled live rock That first tank was ready fast like 10 days I was comfortable with the numbers. (It was really lessdays but I wanted to be sure.)
I have done this a few ways now with the nano tanks. The last one (12G) was seeded with LR
from my little tank and from the lfs
but I had a bunch of dry rock from my old tank and had to wait a long while to get the cycling strong.
