Hi Bro, welcome to this hobby. Firstly, for tank recycling....you can first measure the ammonia and NO level. For initial start-up, these 2 parameters will spike first and subsequently drop to zero. There are few ways to speed up...include liverock, add good bacterias, etc. For the coral, fishes and inverts, please plan what you want to keep and from there the compatibility. For fishes, from less aggressive to fierce fish. For inverts, it is ok but some inverts will eat the other...like some hermit will eat snail, and some snails are harmful to coral, etc. Sorry to confuse you but this hobby needs patience and reading. Lots of things to learn. Pardon me. Just my 2 cents worth of opinion. Newbie also.
