One week into my new 55g. How am I doing?

Hi everyone, Newbie here!

I set up my 55g fish tank last week and wanted to see what you guys thought about my progress. Here's the details:

55g
15g sump
50lb dry rock
5lb live rock
40lbs live sand
RO water
also used Biospira

My question is regarding the ammonia in the tank, here's a picture of the tests that I've done so far.



I can't figure out if it's going up or down. What do you guys think?

PH is good, salinity is also good (using a calibrated refractometer) and everything else is at 0.

Thanks in advance!
