Upside down Jellies

Question
I am not sure you will know this one or not but I am having trouble with cassiopea polyps.  They over running all of my tanks and all I have been able to do is take the rocks out and clean the tank and put new rocks in.  They are coming back from the filtration and bleaching the system is not an option.  I need to find something that can eat them.   Do you have any ideas?

Answer
Jeremy,
The problem with introducing any type of polyp preditor is that when it's done with the polyps it is going to start looking at other similiar corals or invertebrates.

That being said, I would consider using a product like Joe's Juice or doing a kalkwasser injection to burn the individual animals off of the rocks.  This will take some time to get ahead of them, but it is the most effective means I know of for removal of overpropagating corals and inverts.

Best of luck!
