my tank is four months old and I have a four inch sand bed. as time has passed my sand has shifted based on currents, my gobies etc. My 40pd reef has shifted a little and now a few points of the reef are touching and leaning against my glass back. what should I do to straighten out my reef? i realize now that I should have put the live rock on some type of a base but it's too late for that now.
