I use Red Sea Alkalinity Pro titration. I tested my parameters the same time I collected my ICP sample and the ICP stated that my tank was 10.38dkh while my notes state that it was 9.6dkh.
Phosphate (Hannah ULR PPB) states 0.04ppm while the ICP states 0.08ppm.
I don’t think these values are in the stated accuracy. I know there are phosphate standard for the Hannah kit, but I’m curious about making/buying an alk standard. Thanks!
