Is that my salinity?

[Notsolostfish]

Bought a 500ml syringue. And i put the tropic marin hydrometer in there and i got this. My temp is 77. Is that means my salinity is 1.026?

Need a better pic, from slightly above horizontal. It looks like 1.0258, 1.0259, or 1.0260.

Im sorry i dont have a better pic thats where the water ends.

Looks like 1.026.

Fill the 500 to 450.

Have the pour spout facing you.

Some water may spill out so put on a towel.

Very easy to read.

Look at which line on the thermometer the waterline is touching. Whatever line the water touches, that's your salinity. It only works if the water is deep enough for the end of the hydrometer to be floating, not touching the bottom, so make sure that's happenin.

My hydrometer wasnt touching the bottom it was floating. But it didnt touch the line it was brlow the line what does that means.

It means your salinity is slightly less than 1.026. looks like 1.0259ish. perfect

Fill the 500 so when floating the water is at the top.
I just did this reading on one of my systems.
This reads 1.0265.
If the water line is below the 26 the sg is higher.

Like i said i put the hydrometer in, it was floating. But i didnt touch that black line if thats what u meant. This where it stopped. I dont know what i means.

 

[X-37B]

Well we cant see where it stopped.
Fill the 500 so when you drop in the hydrometer the water will overflow a little but you will be able to see it like in my picture.

 

[X-37B]

Ok at the 1.026 mark their are 10 more marks to 1.027. The dot in the middle is 1.0265.
Each line above 1.0265 is 0.0001.

 

[Reef.]

Read the first number you see above the water, looks like it’s 25, then count how many little black lines are between the 25 and the line that is in line with the water, each line is 1, so if the first number above the water is 25 and there are 8 little black lines, then your salinity is 1.0258.

Hydrometers work a little like rulers. So, here's a picture of a ruler.

See how the leaf doesn't reach the 4-inch mark? We can tell that this leaf is under 4 inches long, and we can look at the little marks to figure out exactly how far under 4 inches long it is. Hydrometers work similarly; if the water level isn't exactly one one of the numbered lines, we can count the little marks in between to figure out what the salinity is.
