How much the parameters matter probably depends somewhat on what you keep. I rarely test my nano with zoas and LPS.
My 72x24 parameters
pH 8.1-8.35 depending on time of day....Apex
salinity 1.026
temp 79.4 to 79.9...Apex
Alkalinity 8.5 with slight variations....Hanna
Calcium 440......Salifert
Magnesium 1410......Salifert
PO4 0.06 to 0.1 most of the time but can get up to 0.13 occasionally.....Hanna ULR
Nitrate 5-10......Salifert or NYOS

, it’s been running since March 2018. I have always had higher levels of Mag ! So When I made that last batch of water that was tested, I took the purple bag out of the bucket (dry) and tossed it around to make sure that everything was thoroughly mixed. I recalibrated my refractometer (to make sure that I was doing everything correct) and I mixed the salt with a pump and heater to 35 ppm. So Please let me know when you test your NSW, because I am very curious to see what you get in your test results. Another reefer was the one that told me that he tested NSW and that his Mag was always high too using the same salt. My batch number is 815346, I got this bucket from BRS like 2 months ago. So please let me know when you do it, Thank You and I’ll be standing by.
- this been on ongoing battle.
