Thanks. Jay,It's way to early for the Stone Crab .Your system is pretty much sterile at this point. The crab has little chance of surviving and deserves to be released. Not preaching here just giving it to ya straight. It's gonna take a long time for your tank to mature and patience is number one right now. So You have the Wet/dry hooked up and the water is flowing thru the system ok? Your lights will be fine for keeping fish only. Can you give us a pict or two of how your moving the water thru the setup. Like how the water drains from the tank into the W/D then how the pump returns the water back to the tank. Here are the current FL laws on collecting marine life . The Fish a Game officers are real serious about this.
