Refractometer vs. Hydrometer which one is best for salinity testing for marine aquarium

Thu Jun 13, 2019 11:03 am

I am new to water testing specially the salinity of water. In my marine aquarium i need to have 1.025 constant measurement. But hydrometer is giving me a pain on measuring I always found that my measurement is not accurate so I decided to bought a refractometer. On my research refractometer is more accurate than hydrometer.

Hydrometer is giving me 1.030, 1.028, 1.023 or 1.025 even I clean it multiple times but i'm not getting accurate result. I hope my new refractometer will provide an accurate result.
