Salinity meters/hydrometers

Yes reading from the bottom of the meniscus, I think it is a coralife but the paper insert must have moved because it was floating higher than it should have been. Not a big deal I know you need to compensate on them but the plastic ones are all over the place with the readings. Oh and one air bubble can screw up the arm on the plastic ones as well, make it read wayyyy higher.
