He said ammonia/nitrate/nitrite are all at zero. I never pre-treat my water for water changes either, but I don't have any Rams or any other sensitive fish in my non RO tank.
Depending on what conditioner you are using, I would imagine it might be possible the tank is getting "overdosed" by adding the chemical pre-fill as mentioned above. I also wait until after I add water to add Prime, and I tend to dump it directly into the outlet of the filter just to be safe. I don't know if it matters that much, but it gives me peace of mind.
