Water parameters

Water parameters day 26.
Temperature: 25°F / 77°F
Salinity: 34.45 ppm / 52.4 mS / 1.0255 SG
pH: 8.39 (6 pm)
dKH: 6.4 (alkalinity)
NH3/4: 0 ppm (ammonia)
NO2: 0 ppm (nitrite)
NO3: 0 ppm (nitrate)
PO4: 0.08 ppm (phosphate)
Ca: 395 ppm (calcium)
Mg: 1480 ppm (magnesium)
RedOx: 312mV(reduction potential)

Alkalinity dropped further to 6.4. Also nitrate levels dropped further to zero. Because alkalinity and calcium levels are quite low, I decided to raise them with the Red Sea Reef Foundation Program; A for Calcium, B for Alkalinity and C for Magnesium. I raised calcium to 415 ppm and alkalinity to 7.7 dKH. I'll check the levels again tomorrow.
