Water parameters question

[Yclam]

Today I tested all I could in my tank but I'm still quite new to this. My question is what do you think of those readings.

Nitrates 0
Ph 7.4
Salinity 1.024
Dkh 7.7
Calcium 345
Mg 1130

Are they in good range?

How do they compare to this? https://www.reef2reef.com/threads/o...-reef-aquarium-by-randy-holmes-farley.173563/

According to this my ph and magnesium are on the low side

Yeah, and your calcium, too. How are you measuring pH and salinity, and for that matter, the other parameters? What devices / test kits are you using? Having both Ca and Mg low points to possible low salinity (even lower than your 1.024 reading suggests).

I'm using a refractometer for my salinity and salifert for the rest

How are you calibrating the refractometer: RO or a calibration solution, and if the former use the latter instead. Get a pH meter instead of using a pH test kit. Salifert is good to use for everything else, though.

You were right. I was off by .004 on my salinity. It is now to low 1.020
