Review: A must have for all fish keepers - I highly highly recommend adding Seachem Focus + Seachem Kanaplex to your roster of fish supplies if you don’t already have some. Very easy to use and give to the fish as well as just being super effective. I’ve saved several of my fish (as well as my mental state) with this stuff

### ⭐⭐⭐⭐⭐ Miracle worker!
*by D***L on March 11, 2025*

I don't know what my fish had. Just knew they were sick by the fact that they were laying on their side at the bottom of the tank. Used this every other day after a 50% water change. Mixed with seachum metroplex. After an evening things looked better, after a week back to normal.
