I don't see anywhere in this thread how large the tank is or how many oscars are in it, so just a reminder of 1077's comments on this aspect.
Depending upon the answers, I would increase the volume of the partial water changes to minimum 50% once a week, or more if the tank size is not adequate for the fish. Can't say much more without knowing the information.
