Hi, new to the hobby and I realise that getting a refractometer is not as simple as it looks. I am getting one with calibrating fluid. How is this different than using RODI water? and what if my cal. fluid runs out? any LFS sells them?

Calibration fluid is 35 PPT salt (parts per thousand). For most general purpose, using RODI water is sufficient.

 

The final objective is to get mixed salt at the correct levels.  But there is slightly more to calibrating the refractometer than just using RODI / calibration fluid. I'll update something over the weekend.
