Ammonia still in the safe area.  
I did a WC,  nitrates above 20ppm , so doing another WC tonight.   
It surprised me that It is working.  I figure ammonia would register a little bit.   So I am going to reduce lights down to five, "15 watts  and use only  5 balls.   For a couple of feedings and see.
I have a few other fish I can add to the tank.   But not any real monsters.    
I got some new, sea chem alerts orders, and an ammonia liquid test kit,  first one I bought since 1992.
