Hi fellow reefer. Hope everyone is doing well. I'm planning on changing out my live rock to new dry marco rocks. I'm currently running fallow due to an ich outbreak so there is zero fishes in my tank which is a lps dominated 100 gallon including sump tank. Is it possible to just change out all the rocks. I still do have bioballs and blocks in the sump. I'm asking since my nutrients export requirements are low right now. Cheera
