I have been wanting to swap out my refugium with another tank. It is because I believe it has a slow leak. My show tank is acrylic and it has many scratches. I thought when I swap out the tank I might as well scrub out some of scratches in the show today. Does anybody have any suggestions for temporary holdings of nice corals and fish and what to do with the sand so as I do not lose that biological chemistry. Any help will be much appreciated thank you!
