So many people seem to start their tanks with all dry rock and sand mostly out of fear of hitchhikers which from my experience and the many others I've talked to, getting an actual bad hitchhiker seems to be a rare occurrence. I feel like so many new reefers are missing out on getting a great headstart into the hobby while also avoiding a large part of "the uglies" when they go the sterile all dry route. I just was hoping to start a dialogue to dispell some of the rumors associated with the terrors of possible hitchhikers so newer reefers might consider using live rock to set up a tank (there are many benefits). So what do you guys think? Should people really be as concerned as they seem over common hitchhikers?
