(More customer reviews)Maracyn-Two works very well. It actually cured dropsy in one of my fancy goldfish about 2 years ago. You should keep it on hand ready to use, because you have to act fast (if it is dropsy). It also works well on fin rot and I have used it 3 or 4 times for that. You don't have to be in a big hurry if it is fin rot.
I don't use a hospital tank. I treat the whole 30 gallon tank with this stuff. It does not seem to hurt the beneficial bacteria that get rid of ammonia. It also does not bother the other fish in the tank that are not sick. Doesn't faze them a bit, although you would think so, since it does make the water look a little yellow and cloudy. I can't think of a worse thing to do to a sick fish than to take it out of its home and into a hospital tank. Besides, it takes a month to get a new tank up and running (cycled). Just treat the whole home tank. Will take a lot of packets of this stuff, so the little 8 packet box won't do much good. Get the 24 packets. Don't be afraid to use this stuff. It won't hurt anything.
The directions are pretty good. Read them all, not just on the box, but inside. The diagnostic chart inside is very good. The only thing I thought was vague in the instructions was what to do if you want to do 2 5-day treatments back to back. I think the best advise is to stop after the first 5-day treatment and do the water change and put carbon in, for 3 days. Then after that 3-day "rest" period do the second 5-day treatment. But you probably won't need it. If you do, another approach would be to try a different med, like Maracyn Plus maybe. These Mardel meds are the real deal.
Note this Maracyn-Two is for freshwater. I think there is a separate product for salt water.
By the way, I would not use potted plants in the aquarium. The little bit of dirt on the root ball will have lots of foreign bacteria that your fish have never encountered before. Dropsy bacteria are in dirt. My fish that had dropsy, it started 4 days after I put a potted plant in the aquarium.
