substrate

[digitalsteve]

i found a product at jl for a replacement i noticed they use it at hidden reef for there frag tanks it looks pretty good . if i change the substrate , i will move my livestock and liverock into buckets with filers and heaters running but do i need to wait any length of time for the tank to cycle or once i add my new substrate can i place the rock and livestock back in ? the product i am going to use is reef base marine by redsea.
