^x2 on that.... works great for flatworms, but you must dip with caution... anything that dies off from that stuff (expecially flatworms) can release a chemical that is harmful to your corals/fish... have a fresh (saltwater) bath to dip them into after your 1st dip and then insert back into tank.... when i had flatworms a while ago, it was so bad that i created a tote with my live rock and dosed the $hit out of it for about 2 days, then switched to another tote with fresh untreated saltwater, and i have not seen them since..... plus the addition of my six line wrasse helped a ton also......
it kills zoa eating nudis too. I just did a treatment in tank for them though...haven't used as a dip. I don't think there's any added benefit using as a dip over coral RX or revive.
