Well after much of my own research online:read: but not much personal experience, I decided to come to you guys for the answers.
Which do you use?
A Hydrometer or Refractometer
I know refractometers are generally viewed as more accurate. I would like to hear from people using both who are...
I use a Sera Marin densimetre to control the salt levels. It is at 1023 constantly.
However have today used a refractrometre from a friend and it showed 1026. How is this possible? I assume refractrometre is more reliable but 3 points difference is huge. Any help? Cheers.
