Im in the process of starting my first ever SW tank, and so therefore need something to measure the SG levels of my water. Having spoke to the lads in my LFS he strongly advised that i didnt get a hydrometer, and said he uses one he bought on ebay (my LFS doesnt stock marine gear)
Any other opinions on them or are refractometers refractometers at the end of the day?
Heres a link to the one he suggested.
