I've seemed to settle around .1 and 25 on this build and have only had trouble when intentional deviation occurs. I find I get better colors and overall health just letting the tank do it's thing.
Nitrates can go up safely to 20 and extending water changes will help that slowly climb. Phos can go to .1 safely so, in essence you are in safe range yet
My Goniopora don't like nitrates below 10, so I shoot for 12-15. If I let my phosphates go over .08, bubble algae goes crazy. I shoot for .03 - .06. At these levels I get the best color.
