Hello everyone, I been really busy this last year and unfortunately my tank has suffered the consequences. My sps is gone and I am just left with some favia, zoas, my 2 clowns, and about 200 aptasia in my 20 gallon tank. What would be my best option. I was just thinking of taking out the rock just turning the tank into a bare bottom frag tank. Do I need some type of live or sand or can I just remove it all. Thanks for your ideas guys.
