when i did my treatment, i found it to be less harmfull than it really seems. all my shrimp and crabs including
acro crabs survived. although i saw no real damage caused by the bugs after 4 months, i decided to nuke them neways. it feels good to be bug free.
my doses were less than the recomended amount. 100g total water volume.
i used the 25-50lb interceptor heartworm meds. 1-2 a pill each treatment, 3 treatments total 4 days apart with
skimmer carbon and uv off. the bugs will hang on till the 6th hour and they start dropping. worked well for me.
good luck vic.
