- 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.
Purchased this to treat blue green algae. Now I was treating a 29 gallon tank that only had a dwarf puffer and danios. So while I treated the tank I reduced the water level to half. Make sure you you follow the full instructions.
I don’t know what else to say, but it works.
Used as direction this totally eliminated my mess of B-G algae in about a week. Couldn’t believe how well it worked. Thanks
I purchased this product as well as the other 2 in the trio to treat my newly purchased corydoras as a quarantine method I saw on aquarium coop’s YouTube channel. I wanted to take as much care to not introduce anything that could potentially harm my mollys. All of the corys are now in my Molly tank and everyone is doing well. I will continue to quarantine all my new additions this way. Thanks for sharing your knowledge and helping all of us newbies. I would suggest maybe offering all 3 as a package deal.
