Im a little weary putting anything not made for the reef in your tank, you never know if any metals or other containments may be in it. Its cheap insurance/reasurance to eliminate any unknowns that could get into your tank. With as much as we put into dollar wise not to skimp on such a small part of the total cost as buying the livesand and adding it......what once a year? Compared to scrathing your head and wondering why things aren't working out, I think its cheap compared to all the cost and trouble fixing a problem such as that. Now, I am not saying you can't use it, but why risk your investment?
