Reef Aquarium Startup

Anybody have recommendations on a good overflow for a 220? Ditching the canister filters and going with overflow and return pump.
 
Also how long should the dry rock take to turn into good live rock with just the substrate in there?
 
Also!! Lol sorry for posting so much just want to get this right the first, but a good glue for live to make a cave for the shark. If anyone knows of any recommendations are highly appreciated.
 
Would anyone recommend a feeder tank for this shark, I know primarily it eats worms and crabs, but can it live healthily on anything else? Or would it have to eat live worms/crabs
