[NewMariner]

Does anyone know how to get rid of calcuim deposit in saltwater fish tank without affecting the salinity of the water?

Is the tank full or empty? In an empty aquarium use a vinegar and water mix. Scrub the area and it should come off. In a full tank you could also use the vinegar water mix but try to minimize how much vinegar goes into the water column. If the tank is large enough, a bit of vinegar will not effect parameters.
