“This Product was bought to treat Columnaris bacteria species. yes it states this in the info, however the disease I was treating looks like a cottony growth (Fungus) but in fact it's hard as a rock. this product killed the gram negative bacteria that was causing the growth. It will turn grey in colour when the product is working. Unfortunately the growth did not fall off the fish. I had to remove it by hand. fish can now eat again. Duration was 3 treatments every 3 days, didn't Kill off bacteria in filter over the duration of treatment.”
