As with everyone else here, sorry to hear about your loss. This hobby is all about learning, reading, and taking it slow. I know your pain because I just lost about 80% of my corals from a tank transfer which equates to a couple of $$$$ (to say the least)....i too was disappointed and feeling down. But if this is something you really want to do, don't give up. There are always gonna be ups and downs in this hobby. It is rewarding when you finally get your tank to where you want it or envisioned it to be. Just take this lump and keep trekking.
