I have a 4ft by 3ft by 2ft and the calculation works out 28 tablets does this sound right?

Sounds about right to me I know I used a lot per dose. I think I used 18 on a 3ft x 15inch square tank.

Has this product cured anyone's fish of Dropsy?

sadly not many seem to understand that Dropsy is a symptom not a disease. Dropsy is a symptom of Kidney failure and only antibiotics such as keneplex combined with salt (Epsom and aquarium salt) treatments have been scientifically proven to combat and reverse it. but it all depends on what is making the kidney fail. Internal infection, parstie, genetics, poor water? you have to find the root reason as treating dropsy you are only treating a symptom not the illness it's self.

Hi has anyone used this on Oscar hole in the head? How did it go? Did you have other fish in the tank during treatment?

Hi don't know if this helps but my xl severum had bad hole in the head and this treatments works 3 day treatment but need to remove carbon from filters

Is this for all fish? does the packaging say it's not for any specific fish types? specifically cory dora and yoyo loach. thanks

I’ve used it with sensitive fish, Discus mainly, never had a problem, even used at 3x recommended dose for a resistant strain of infection without issues. The general rule is take care with scale-less fish such as loaches, but mine always were ok.
