The last missing value: phosphate. Meet the PO4 Director.

The PO4 Director extends the ION Director to automate phosphate measurement in reef aquariums. It connects to the ION Director’s AUX port, shares its sample line and uses the free pump of its doser, with fully automatic calibration using the existing reference liquids. Expected in spring 2027: accurate phosphate monitoring with only one reagent and low operating cost, without additional dosing hardware.
