Salinity And Warmed Water

[BigReefer]

what are ppl keeping there salinity at 1.025 or 1.026 ... or something different ??? does it matter if u have a sps tank or ... a mix reef ... I know with a fowl they go much lower ... just not sure on the mix reef situation ... I been keeping at 1.025 but i know some have it at 1.026 .... at 1.026 would there be more trance elements?

I have heard rumours of zen masters that can dip a finger in a tank and tell the salinity. I'm a noob and use a refractor meter but try to keep it 1.023 or over and under 1.026 if I can.

Oh, so you are saying to just use my RODI water and 0 out the meter to calibrate it?
it is a nice refractometer but, I saw another member had got the same one and neither his or mine came with English inst and my Chinese is pretty rusty!
LOL

Yes sir. I use a red sea, and as long as it's not one set to 20 degrees, or can't ATC I'd imagine they are all more similar than not. RO, 0 out, and test away. Every once in a while check it's still fine. I've read all sorts of posts on forums that mine specifically is top end but a pain to calibrate so I was reluctant. MY EXPERIENCE, I feel like posting on all those posts blah blah blah internet hot air cause it's been rock steady.

Well thank you for that info.
I will definitely try it out this weekend!

mine was calibratered when I got it (thanks sewerat) and I have checked mine a couple of times and it hasn't moved...I don't bother checking any more..maybe I should but the tanks are doing great...

 

[heath]

at one of the frag fest there was a contest to see if ppl could tell the salinity by tasting the water, maybe we should it again...

i hope they got cool t shirts again i love to buy more

It's more than fine to use RO water. Hell Tap water. I've compared all 3, and it will 0 out with all of them.

You cannot accurately calibrate a salinity meter with RO water.

You can check that it measures 0, but we don't care about that. We want to know if it reads a higher range accurately (1.015-1.026) lets say. That's why there are fluids at different values for calibration.

Ok. And does @unibob carry the calibration fluids? ( TDS and / or Salinity )?

I will 100% not dispute this.

Which is why I said from what I've done, I've used the fluid, used RO, and even used tap. Zeroed, out, and tested water, and after baseline of 0 with all these fluids, the tank water read the exact same. Had a friend bring his

If there is another variable at play that.

Further to that. I mix my salt and to exact amount with exact temp, I get also almost exact actual salinity.

Perhaps this is my specific refractometer.
Here is the manual. Have a read as it explains differences with refractometers, then explains how to calibrate this one.

Either way I will absolutely check out your manual. like I said, mine only came in Chinese. lol
the one my daughter got me was a Patec ATC refractometer.

Oh and thank you @Nighthawk26 for posting the reference link.

Can I bring my refractometer with me to frag fest and test it against a known value in one of the tanks?
