Review on Seachem MetroPlex Metronidazole - Effective Treatment for Parasites and Bacteria in Saltwater and Freshwater Aquariums by Kevin Hole

Love this thing! My black eye developed Brooklynella and used this treatment for 3 weeks as recommended. He cured the disease as described without harming any of my corals or invertebrates. I have frog spawn, torch, duncan, zoa, and leather cabbage, as well as mint shrimp, emerald crab, and turbo slugs. It didn't harm them at all! I would highly recommend this to anyone needing aquarium treatment that a hospital aquarium does not have or is unavailable!
