I was using a simple hydrometer. I would take a large cup of water from the sump to try and test without any water flow, and it just wasn't working out. My refractometer came in yesterday and sure enough my salinity was about 1.029. I got it down to 1.027 yesterday and today I will going for 1.025. Even with the high salinity though, everything seemed to be doing really well. Mother nature is one tough mother!
