Got rid of a nematode infestation
I had a nematode problem in one of my tanks, so I used this stuff and treated all of my tanks since they had all been cross-contaminated. It definitely worked and I still am using it from time to time as a preventative to make sure the problem does not happen again. I rated it only 4 stars simply because I did lose a couple of fish in the process.
Rating: 4 stars
