Troy, I think this to be true given the way we currently use them. I think shallow sand in the tank and a remote DSB is the way to go. With the remote bed, management becomes much easier. I think the potential plankton resulting from these beds is great, and if we could replace small amounts over time, toxic buildup could maybe be avoided.
