Glad to lend a hand Don. Unfortunatly my knowledge about SAP comes from personal experience. I had a very nasty outbreak of it after burning fish with Superverm. The fins on many fish had big globs of SAP growing on the edges. that was an easy fix....I sedated them and trimmed the fins! The cut edges were treated to prevent re-infection and all the fins grew back normally. Treating SAP on the body is much harder and needs to be watched closely for reoccurance. I treated that before too. Sometimes sucessfully.....sometimes not.
