Since the salinity of marine water in an aquarium must be kept constant, the aquarium water should regularly be checked accordingly. The water to be tested is filled into a sufficiently tall water glass, and the scale of the immersed hydrometer is read off on according to its immersion depth.

Aquarium has been having problems for nearly 6 months and finally tracked it down to this POS reading 20% lower than actual.

It works kind of but is so hard to read it's not worth it. The longer I've had it the less accurate it is becoming

I’ve been using this for about a year now and works great. The great thing about this is it can’t go out of calibration and is calibrated for salinity at 25 deg. Celsius so it can be used as a calibration medium which is nice. The corals and fish seem to approve.
