did she wash the media with aged tank water? if not she washed away all the good bacteria...and to keep a happy pacu you will need atleast 600gallons otherwise it will go crazy
If you can source it try to find some bio-spira, I added it to my tank and it cycled in about 24 hours. Just make sure where you buy it from has it refigerated otherwise the bacteria will become active and start dying off. If you are more than 10 minutes or so away I would consider bringing a cooler to put it in to make sure it remains cool as well.
