This stuff saved my fish's life. Who could ask for more.

Pros: Works

Cons: Expensive

This stuff is great. It's the heal-all for many fish ailments. It also makes your water smell good! It's very safe for your fish and hard to over-dose the tank.

Pros: a wonderful, safe product

Cons: none

This is not a cure-all, but will help with some fin issues. I use this in my pond when the spring is starting. It seems to help the transition for my fish, sort of as a general tonic. I also use it for split fins, and it seems to help them heal without issue. I have also seen repeated use set back my biological filter, so not for everyday use.

Pros: Easy to Use

Cons: Not a Cure-All

I use it everytime my fish get sick or have any problems, works fast and isnt costly!

Pros: Works fast

Cons: none

I admit I am not a fish expert, but every time my oscars have been ailing with no obvious cause--even looking on the brink of death--a splash of this in the tank revives them! I'm not sure what is in this, but it is amazing...my fish will go from surface-floating to happily attacking their food within hours! I always keep a bottle of this on hand.

Pros: Works great, reasonable price, easy to find

Cons: none
