Go figure, Refractometer was off.

Thank. I'll look into it. Where is the best place to get this solution?

 

Which is exactly why you should verify with a hydrometer.

 

a hydrometer can be further off then a refractometer so how would that verify anything? the only way to be 100% is use a electronic SG probe.

 

1.025-1.026. NSW averages around 35ppt (1.0265), which is what I really try to achieve. However, I'd rather be a little short than a little over.

 

Why?

 

Hydrometers are notoriously inaccurate. They're susceptible to air bubbles, temperature effects, and poor calibration.

 

Temperature can easily be corrected for by calculation. As for air bubbles and poor calibration, do you know this from experience or do you have information from reputable sources?

 

Collective experience. Ask anyone who's been in the hobby for years.

 

because a hydrometer uses buoyancy and isnt temp compensating so when your mixing your SW if its not room temp then its going to be off or if you dont rise your hydrometer after every use then the salt can effect the meter. There is many different things that is why they only cost $6-$20 its good to get you started but to be accurate then a SG probe is the only way to go. but a refractometer will work cause it measures of an index of refraction which is the actual composition of material in this case the SG.

 

lol. Thx for the chuckle!
