I used this as directed along with the marycn 2 and
it worked. My betta was very sick and I thought he would die. Now he is completely health. I would totally recommend this.

Pros: works great

I bought this because the Guppies I bought a few days before developed fin rot (And turned out to have MANY other problems)
Anyways the instructions were very easy to understand and the information booklet that came with it were SO helpful! They come with a diagnose it yourself pamphlet that can help diagnose the problem with your fish and then suggest their product that would help cure the fish.

The medication didn't work on my Guppies, but it did work on my Panda Cory's (Which contracted one of the other illnesses my Guppies had.)

Pros: easy to administer

Cons: didn't work
