What's not to like? by racindog from Louisville, KY08/15/2014
Great stuff. Fresh & excellent quality & works good at a good price.
Worked great! by Greg from Kentwood, Michigan06/03/2014
I have had bacterial problems with most of my fish and this is by far the best anti-bacterial product I have used. And its pharmaceutical grade.
Lightning fast shipping. I got it the day after I ordered it and I live in Michigan!
