Yah I will be doing a WC tomorrow after collecting the refractometer. And then I will be getting the critters
Yah I was also hoping that my pH should be above 8 because I have lots of surface agitation and have proper ventilation too. Maybe the meter needs re calibration. They did send two calibration salts (4.01 and 6.86) but the meter is only accurate upto 1dp so I guess it is missing the points plus the solution is very sensitive to temperature (that's what I found from the back; even two degrees can make the solution go 2 dp offs). Any suggestion on the calibration? I was thinking of taking it to LFS and calibrate with their system.
