Cheryl got me thinking in another thread and I wanted to get some additional information here. I'm about to receive a number of new acroporas at the end of this week, and I wanted some advice on which dip to use. I have a bottle of Coral Rx, but have seen a number of other suggestions out there, including some for Bayer pesticide. These are the acros that are on their way, including one blue lokani that isn't pictured. Which of these are considered "smooth skin?" Do smooth skin need special attention? Cheryl, thanks for prompting me to think about the dipping process in more detail!
