I've never used it by itself, I always do coral rx followed by a rinse then an iodine dip and maybe FW after that depending on why I'm dipping. But it's always been part of my dip process.
It is a good product, if this is your first time using this product, make sure you follow the directions properly and it will work fine. If you don't, you know pretty quickly
I use this dip as my first dip for all incoming corals. After of 7 days in QT with Flatworm Exit treatments, I do a final dip in Coral Rx, 1 more day in QT and then move it to my main display.
Some corals may look a little funny after the Coral RX dip. Don't fret too much, most corals will recover.
