Well I guess it's time to start a new thread since I'm upgrading my 50g zoa and chalice dominated frag tank. Retiring this thread

The 90 is a center overflow, thinking I'm gonna change my lights up to two ai sols and 2 48" t5s. That's worked well for me in the past, and should be enough light so the zoas and chalices don't freak out too much. Collecting rock to figure out a scape, will be adding my lps that is currently in my 125 g sps display to this tank. Finally, some room to grow, at least for non-sps. Here's the sps thread for reference
