Just thought I would post some pics to demonstrate that Purge will not harm acros. This is an infected smooth-skinned acro that I was afraid to dip because they're so sensitive. This pic was taken in September before treating with Purge. It was losing tissue on the left side and I expected it to get worse.
After the Purge treatment, color has returned, tissue has regrown, and it has completely encrusted on the plug. It's a happy acro!
