Hello fellow reefers. I would like to do some extensive aquscaping. I would like to remove all my rock from my tank when I do my water change this weekend and rearrange my rocks for better water flow and movement in my 150 deep. When I get all the rock removed I would also like to spread the sand more evenly because over the 5 months the tank has been running the sand is somewhat uneven. How many problems would this cause? I don’t want to cause any problems. Let me know thanks.
