I want to make an experiment to see if sodium silicate will cause a phosphate false reading with the Hanna PO4 ULR.
@taricha tested with the Hanna Phosphorous ULR, and someone said that although the phosphorous checker doesn’t have much of an interference, the Phosphate Checker does.
I will make 200mL of saltwater in a glass beaker with my magnetic stirrer.
I will test phosphates and silicate prior in the Red Sea Blue seawater mix.
Most likely the starting phosphate will be at 0.00ppm.
I will then spike the silicate to 2ppm, and test the phosphate to see if there is a rise. I will not dose phosphates at all. Let me know if I should to make the experiment more accurate.
This is the sodium silicate I will be using:
