Using 145g of Salinity Salt mixed with 4L of RO (no DI) batch bought from the store:
Temp 22.4C
SG: 1.026 (Selbon refractometer - checked calibration today)
Salinity: 35ppt
pH: 8.77 (pinpoint pH monitor)
Alk: 3.17meq/L 8.9dKH (Hanna colorimeter)
Ca: 330 ppm (Red Sea Reef Foundation Pro)
M: 960 ppm (Red Sea Reef Foundation Pro)
(I validated the test kits with other test kits last night and a reference sample).
Okay, so it's not just my water that is causing this problem. This constant testing is getting time-consuming and expensive... however, I won't subject my animals to this mess and will need to keep trying and testing til I get more appropriate results.
