Red Sea Reef-spec Seawater Refractometer Substrate Adjustable flow regulators control amount

Adjustable flow regulators control amount of air entering reaction chamber to produce perfect amount of “skimmate”

000 ppm (mg/L) with added traces of Iron

’ This feature splits the rear and front of the tank via a glass panel positioned 10cm off the rear of the tank

Push the bubble counter stem into the top of the fine adjustment valve - it will seal however is not a 'tight fit'

Most refractometers used within the aquarium hobby are not specifically designed for reef aquariums and use an algorithm for the measurement of brine (NaCl rather than seawater) and at a temperature of 15oC 59 0F rather than 25oC 77 0F. Thus, a
