I wanted to ask the more experienced one's this question prior to performing it. I was told I could take out my rocks corals etc and dip them in a fresh RO-DI to try to remove the flat worms. Is this true or do I risk killing any beneficial growth and injuring the coral. I DO NOT want to use flat worm exit in less it is a last option for me. I have a 29 gal BioCube

Yes it may take several treatments.
