refractometer or salinity monitor

[seranko]

Hey guys I'm trying to decide what to buy... a American Marine Pinpoint Salinity Monitor or a Captive Purity Refractometer with Calibration Dial... What do you guys recommend me ????

Thanks

Refractmotor is my suggestion. Unless you have an extremly small tank salinity itsnt going to change wildly over a short period of time so a monitor isnt really neeeded excempt for those who want instant results.

If you get a refractometer, i would suggest getting one that has auto-temperature calibration.
