substrate change

[digitalsteve]

hey guys , i have a 10 gallon nano reef going and i am not really happy with the sand bed , i think it might be too fine . every time i add something in there i notice a lot of particles floating around for awhile. i think this may be contributing to the ill health of one of my fish .
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 using the existing water from the old sand based tank. ? the product i am going to use is reef base marine by redsea.
