Marko,

I would either add single small pieces one at a time a week or so apart, or take Troy up on his offer so to minimize any cycle that adding 60% more rock in not a very large volume of water would create. If the rock has been in the LFS tank for a while, maybe ask for a water sample, if the sample reads zeros then you know the rock should be OK. It will then all depend on how long it takes to get it home. If you could have a water cooler full of preheated water in your car, you could buy the rock and have it back into water immediately and should be able to aviod much of a cycle.
