I like this medication. It works well. It’s similar to Maracyn. I’ve used both with great satisfaction. I would recommend either product.
This stuff works wonders. The med trio that Cory suggests is the absolute best thing to happen to my fish keeping hobby in years. It covers just about all the common stuff and it's super easy to use. We don't place a fish in any of our tanks until it's been through QT with the med trio. Erythromycin is a huge part of the trio taking care of the bacterial infections the commonly plague stressed and recently shipped fish.
I’ve used this for several years, always lowest prices and great customer service!
I feel better able to treat my fish if they should get sick, and I also now have tools to aid in prevention of most disease through quarantine. Thank you.
