[Jaws]

Right now I have a 4or 5" sandbed in my 90G and I only plan on having a 1" sandbed in the 180G and that's only in areas where there isn't any live rock. The equipment that i'm using in the new tank is top of the line too. Hopefully that will make a difference. I don't know what to do about my refugium though. Almost every refugium that i've seen has a sandbed but then like Brad says, it's just another nutrient sponge. There's got to be a way to battle dinos. It's not like it's a new problem and there seems to be a number of people with the same problem.
