ok. i have a living sea 8" hydrometer plus and a instant ocean hydrometer. when i use them i get different readings from the too. I get like a 1.006 on the thermometer one and the one you fill up shows 1.012. exactly how am i suppose to fill it up. does that matter or what? and second which one is correct or am i doin something wrong????

Re: salinaty and specific gravity
This is one of those questions that is best answered by the salt water fish group.'Dear Lord,' the minister began, with arms extended toward heaven and a rapturous look on his upturned face. 'Without you, we are but dust ...'
He would have continued but at that moment my very obedient daughter who was listening leaned over to me and asked quite audibly in her shrill little four-year old girl voice, 'Mom, what is butt dust?'

Re: salinaty and specific gravity
In my very limited experience with hydrometers, sometimes the ones that you fill up with water can have air bubbles on them, causing a higher specific gravity reading. I agree with PhishPhreek, you'll probably get a more knowledgable response on a saltwater forum like marshreef.Scarecrow : I haven't got a brain... only straw.
Dorothy : How can you talk if you haven't got a brain?
Scarecrow: I don't know... But some people without brains do an awful lot of talking... don't they?
Dorothy: Yes, I guess you're right.

Re: salinaty and specific gravity
With RO water you will get 1.0 specific gravity.
If you are able to get any RO water this is how you can check to see how accurate your hydrometer is.

Re: salinaty and specific gravity
Like armthehomeless said, air bubbles can really skew your readings. Fill the hydrometer up a few times, then check for air bubbles sticking to the pointer/arm thing. Also, make sure the water temp is in the correct range for an accurate reading."Millennium hand and shrimp!"
