The nitrogens he speaks of are:
ammonia NH4 (?)
Nitrite No2
nitrate No3
As said, the ammonia and nitrite levels should be zero, telling us they are acceptable means little or nothing to us. We have already estabilished that you may have recieved some less than accurate advice from Petsmart, so until we know what you or they consider acceptable we really don't know much.
It is very common to get flawed advice from well intentioned pet store employees. many do not know any more than what they have read on the products they sell, and all of those products are not necessarily the best solution, some are not even close to being a good solution as with the Ph modifier you have already tried. This does not mena you should quit listenng to them, only that you should research well before deciding what to do. One of the reasons the nitrogen is so important is that in improper levels it can effect PH to some degree, it would also be amuch more logical explanation for your fish deaths, as PH is usually only the culprit when ther have been drastic swings over a short period of time.
