Erm...rodi water can calibrate already... Bcos it is supposed to find the zero salinity point right...

Yup I know bro. But if you do some Google search, the result is not accurate using rodi. There's quite alot of such discussion over calibration and majority have experience inaccurate result using rodi.

Use distilled water set the refractometer to 1.000.

The refractometer is only as accurate as your eye permit unless you are using a digital one.

I'm using Distilled Water too.

That's what the lfs recommended too.

Agrees with xiggie. The fish/ coral do accept a slight variation of salinity, hence need not be very accurate. In fact, salinity will varies depending on temperate.
