I agree Flower, consistency is key. I can only speak for my own experiences, as can you. I had a deep six hydrometer, that cost me maybe $6. I had heard, from many others on this site, that the readings can be off. I asked, well are they normally higher or lower? Thinking maybe I can do the math and compensate. The readings vary. What you believe to be consistent may not be. With all of the money that we put into these tanks, who the heck wants to worry about the extra $30 for an accurate instrument? Not me.
My Red Sea hydrometer looked very cloudy because of exposure to the salt over the years...so I purchased the deep 6, what a waste of my $6.00. The instructions said to season the hydrometer for 24 hours before use, it didn't help... and it never read the same thing twice even moments after, so I went back to my little cloudy Red Sea one for many years. When I found this site, back in 2009, was the first time I had ever heard of a refractometer. I asked the pet stores and they hadn't either. One place, a mom and pop store, told me it was an outrageously priced gizmo, and a regular hydrometer was just as good for so much less....however, at the time they had never heard of hypo for getting rid of ich either. The store owner told me all SW fish tanks had ich, and only weak fish would be contaminated and he also sold those reef safe remedies....now I order my critters on line. I use the pet store for equipment and salt purchases only and 99% of the time they don't have the good equipment either.
Like I said, OP had a sort of emergency and needed to know the SG right sway like a week ago, and the hydrometer was the fastest thing to be able to get and use. I really wish the pet stores would push a good starter book as hard as they push for the other crap they sell. There should be one in those reef ready complete tank set ups they sell and keep their flake fish food....LOL..in a perfect world.
