I am in the process of starting up a new IM AIO 50g lagoon reef at work. So far I have rock and the latest IM Heater. My next purchase will be sand, and salt, then I can add water. I am curious if anyone near Provo Utah has live rubble rock from a well-established tank that they have kept cryptic (in no light.) that might be willing to share or that I could buy off you cheap. I am debating on adding that to the back of my AIO for the beneficial bacteria and pods. (I can't wait for BRS's Part 2 on the Bihome testing!) I will try to keep my progress posted. I also share on insta @taylored_projects. Thanks!
