Along with the advice Kitty Kat gave I would recommend you use an alternative water conditioner. I have used Nutrafin Aquasafe in the past myself and found it very counter productive, the products design flaw is that it doesn't neutralise ammonia but in neutralising Chloramines(sp?) it produces ammonia as a by product of that neutralisation but does not then detoxify the ammonia it produces to make it safe for fish. I found myself frantically doing water changes when I was new to fish keeping as my Ammonia level was through the roof and the more water changes I did the higher the Ammonia readings were going. In fact it got to the point I could do nearly 100% water change and "neutralise" the chlorine and chloramine and then perform a water test to find Ammonia at 2ppm!
I would recommend something like Seachem Prime or Tetra Aquasafe, both are great for either Fish less or Fish in cycles, the first being the preferred method for myself.
