Adding LR in stages??

[justinl]

lfs rock is rarely cured. I got a large portion of rock in the beginning and cherry picked slowly after that. When i made additions, I cured it at home in a bucket. real easy and it ensures there is no spike upon addition. just submerge the rock in a container (tote, bucket, spare tank, etc), throw in an air line and heater and let it sit a few weeks. If you're really anal about it, you can test nitrogen levels, but i don't bother. I like to cure in a spare tank because it allows me to inspect the rock for any unwanted hitchers during the curing process.
