So I just bought a refractometer & 4 stage RODI PLUS with water saver kit that were on sale on Bulk Reef Supply's site. Unbelieveable as to how inaccurate that hydrometer was....and I've been using it all this time! Hopefully I will see less algae growth and my birdnest coral will start showing signs of better health with better water quality now....
 
Make sure you by some calibration fluid too. Test the refractometer every once and a while as they too will get out of calibration.
