I am looking into doing a remodel of my 75g. I dont like the rock work in it. Was wondering what steps I should take to keep my few corals and fish alive during the remod. I have sand in the tank also, i would like to get that out for when i put the new rock work in. My rocks right now have hardly any if any coraline algae on them. I basically want to keep the sand alive for the bacteria and start "fresh" with the rock.
