I saw a guy hook a large planted macro tank and tons of rock and shrimp and filter feeders up to his reef tank and ran mud in the macro tank. The Macro tank was another display tank in another room not as pretty as the reef but it was a pretty legit looking display and added a serious amount of volume and bio filtration to his whole system. I liked that idea and might have to steal it.

Sorry for the thread jack Tristan... Bump ha ha.
