my fishs behavior

Question
I have a small fish and i've had it for quite a while . I used distilled water for a month and a half then started using drops to make the tap water safe , but when i used the drops my fish started to swim up then sink . I don't know what to do.
Please help.

Answer
Hi Alberto,
  Hmm... it could be the water, but it could be a coincidence.  It is important if you are using tap water that you add the drops to the water (in a bucket presumably) before putting that water in the tank.  Are you doing that?
