Steve, I've tried it on one or two occasions. Kind of hard to do plumbed in with my reef - one or two species seem to end up dominating. I still have turtle grass in my 60 gallon cube along with some C.prolifera. The requirements for all the different macro algaes are not super well known - I also had a TON of halimeda that I removed last month and threw in with my mantis - calcerous algaes have needs similar to some stony corals albeit on a smaller scale.
Look at pictures on reefcental of a user named 'plantbrain' he had a really cool saltwater planted tank - I think he's a plant biologist.
