Water parameters

Water parameters day 26.
Temperature: 78 °F
Salinity: 34.4 ppm
pH: 8.41 (8 pm)
KH: 6.7
NH4: 0 ppm
NO2: 0 ppm
NO3: 0.25 ppm
PO4: 0.08 ppm
Ca: 400 ppm
Mg: 1440 ppm
RedOx: 312mV

I'm using this calculator to determine the correct balance between dKH and Ca: calculator. Both dKH and Ca are quite low, but balanced. I measured Mg accurately. NO3 dropped significantly from 4 ppm to 0.25 ppm in the last days. I still have a lot of algae in the tank.
