PARmeter Apogee

[jerlo reef tank]

Hello everyone,
I ask myself a question, I just received my PARAMETER Apogee SQ200. I read on their website that the measurements may have% errors depending on the water temperature, the measurement angle ect ...
Does the salinity of my water affect the results?
In absolute terms, if I fill my aquarium with tap water, will I have similar results to seawater

Salinity (dissolved inorganic salts with normal seawater composition) will not significantly impact such a device, but if there are light absorbing organics or light scattering particulates in the water, those will. Of course, that's not an "error", but an actual result.

[QUOTE = "Randy Holmes-Farley, poste: 4575936, membre: 45227"] La salinité (sels inorganiques dissous avec composition normale de l'eau de mer) n'affectera pas significativement un tel dispositif, mais s'il y a des particules organiques absorbant la lumière ou dispersant la lumière dans l'eau , ceux-là vont. Bien sûr, ce n'est pas une "erreur", mais un résultat réel. [/CITATION]

Ok tks Randy
