Can't tell the saliniyy

[Shaina Carey]

I suck at checking the refractometer. Can anyone tell me what my salinity is at? Calibrated it with distilled water before testing it with saltwater.

That’s 1.027, as long as your refractometer is one specifically designed for saltwater, where calibration with RODI should be ok.

Thank you, lol. I have bad eyes, so it is hard to read the numbers. Yeah, It is only for saltwater.

Typically salinity refractometers will not give accurate results when calibrated off of rodi or distilled water. Do you have any refractometer calibration solution?

What make is it? You can make a diy salinity calibration solution, to be sure, if you are interested;

I have used this recipe before it works great. Makes a lifetime supply too haha.

And it’s silly cheap, I like cheap :)

I feel your pain with bad eyes, I have a hard time reading those things.

In doubt i use Tropic Marin hydrometer at 25c in my 5 gallons wc, in sump or in tank... and calibrate my refracto whit it.

I will buy some. I have no idea where my bottle I had went off too. I can use tap water in the meantime.

This is the refractometer I have. https://www.amazon.com/gp/aw/d/B07ZHZY2J1?psc=1&ref=ppx_pop_mob_b_asin_title

LOL, I just made a post regarding how much I like not having to calibrate the TM Hydrometer

I still had to zoom in to read it.

That gives me an idea, if I can take a pic like the OP did and blow it up I will actually be able to read my Refractometer

Yup ! No more doubt on something so basic and "kind of" important :beaming-face-with-smiling-eyes:

 

[Shaina Carey]

I checked my hygrometer and it is reading about the same, lol. Should have used that too.

No not this one :beaming-face-with-smiling-eyes:

Edit: if you have 2 or 3 equipment that tell you the same reading.
I guess those are telling you the good mesure.

 

[Shaina Carey]

Anyone you suggest? My LFS had a few

See my edit.

Suggestion: Tropic maric hydrometer (about 16inch high) but never have to be calibrated.

I’d be using a calibration solution with that one, tbh
