Ca-490 ppm (no supplimentation)
KH-9.3
SG-1.025 (too high?)
pH morning-7.8 evening 8.0
no3 and po4 barely perceptible
added another power head for surface circulation

Calcium is a tad on the high side but that will correct naturally.
KH of 9.3 equals 2.65 Meq/L Alkalinity, dead on.
PH is on the low side of normal but acceptable. What kind of substrate do you have? Aragonite and live rock should bring your PH up a bit and act as a Ph buffer.
