The test solution color of a new Salifert phosphate test kit is compared to that of a kit that has been in use for six months. The old kit indicated a somewhat lower phosphate level (see picture). The new kit gave a phosphate concentration of ~0.5 ppm for a new batch of Instant Ocean spiked with ~0.4 ppm phosphate.
Just making sure that I am in the ballpark with phosphate levels because I am trying to culture cyanobacteria which is another story in the making.
