  • Treats Bacterial Infections
  • Plant Safe
  • Invertebrate Safe

Maracyn's active ingredient is an antibiotic called erythromycin. It provides relief from bacterial infections such as body fungus, gill disease, fin rot and popeye in freshwater aquariums.

The savings come in the large 24 pack or larger over the traditional API Erythromycin. Each packet treats 10 gallons. The 60 gram bulk container treats 1,000 gallons. We recommend using an airstone in the aquarium when treating with Maracyn.

Works like a charm

I keep this stuff on hand just incase! Fast reaction time with effective dosing clears up anything before it gets out of control. A must have for any fish keeper.

Saved my fish

An excellent product (no surprise I got it from Aquarium Co op) that kept me from having to euthanize my fish. I wasn't sure if she could be saved but this did it.

I saw the blog about algae and the meds worked perfectly!

Make sure to get the large dose if you have a big tank. It need a pouch per 10 gallons
