Hey! So I’m new to having an aquarium. I have had two 75 gallon tanks (one fowlr and a mixed reef) for about a year and half now and want to upgrade to a Red Sea Reefer 750 (200 gallon). Should be turn key and go but what is the safest and correct way to relocate corals and fish. I want to us sand and rock from these tanks but will obviously need to add more live rock and and sand. Thanks in advance I have about 900$ in corals I love.
