Over-run by Ricordea's

[Jaro]

So my tank is slowly being over-run by brown ricordea's. I thought they were neat at first so didn't touch them. Then they kept spreading so I "harvested" some to keep them in check but I seemed to do a lot of damage to the reef trying to cut them off. Knocking stuff over (darn clown fish kept biting me when I stick my hand in) so I stopped cutting and now they are EVERYWHERE!

I have some SPS corals (motipora I think) but they are now getting taken over by the ricordea so I need to either get rid of the hard corals and let the ricordea take over the whole tank or get rid of the ricordea so I can grow SPS. Anyone have ideas how the get rid of the ricordea??

If there is no easy solution to getting rid of the ricordea I'll want to trade my SPS for other corals that can compete with the ricodrea and just go with a soft coral tank.

Not sure how to post pics but I'll take some post when I get some more free time.

All suggestions & ideas welcome!
