NEPTUNE SYSTEMS APEX PROBE CONDUCTIVITY/SALINITY CALIBRATION SOLUTION 53000 µS (5 PACK) D-D The Aquarium Solution We have added a gasket

We have added a gasket to seal the area between the sump and the input plate to prevent salt creep build up

The sliding color chart along with the six-cavity test plate allows for easy reading and comparisons of several samples at the same time

Every aquarium is different so the IQ-Level feature of the COR-20 enables you to set a customized minimum and maximum flow rate for your specific aquarium’s needs

2x BSPP x 2" Slip Unions

At the touch of a button the Vectra pump will temporarily pause the current mode and idle allowing food to be added to the tank without being cycled into the overflow and filtration

NEPTUNE SYSTEMS APEX PROBE CONDUCTIVITY/SALINITY CALIBRATION SOLUTION 53000 µS (5 PACK) D-D The Aquarium Solution We have added a gasket53000 S Conductivity Calibration Solution Use this calibration solution to calibrate your Conductivity Probe and PM2 for saltwater salinity monitoring applications. Conductivity probes can be used for many different functions from letting you know the salinity of a tank to the quality of RODI water. We suggest calibrating conductivity probes once every 3 6 months to keep readings reliable. 447 S Conductivity Solution Used for calibrating conductivity
