As you might know I am restarting my 20 cube. I only have 2 fish currently an clownfish and wrasse. Also only a few corals. I’m planning on trading in the fish to love the reef. I might give the corals to a friend until my new tank is up or the store. I am buying new rocks to do a much better aqua scape and also new sand. I would love some advice on how to restart a tank or tips from anyone who has restarted a tank before. Thanks
