It works


Yes it's pricey, but it works, I put it in their food every day, along with the focus and garlic guard, and it gets rid of the parasites and keeps them gone, I have a 360 gallon coral reef salt water tank, it's too expensive to treat the tank, putting it in the food, ever morning, keeps the fish healthy.



I know it is VERY expensive, but after losing 5 fish to ICH wasting my time and money on that other crap I broke down and bought it. In three days all spots were gone and the fish are looking much less stressed. No scraping the wood and gravel (or each other for that matter) trying to scratch. I also used more than recommended. I did the 100mg every other day, but on the off day I fed it to them in their food.

The Best


This is the best metronidazole I have used ever, 100% pure no excipients but I use 200 mg each 10 gallons every 24 hs.
