HTown Reef - 200g Waterbox Reef LX 270.6 (SPS Dominant)

If you test the salinity it should move in little temp swings. Think it’s apex correcting for temp changes and giving weird numbers.

To be honest, my salinity values have confused me the most out of any other. I have both a Hanna checker and a good quality refractometer, both calibrated today and reading different values:

• Hanna: 1.025
• Refractometer: 1.027

While I'm inclined to believe the Hanna checker more so than the refractometer, it doesn't make me confident in my values. I know that as long as I keep them stable it's relatively fine, but if they're too far outside the normal band of salinity, that's what makes me concerned.

When you say Hanna so you mean the pen style with the graphite pickups or the bench style optical one?
I only ask because I have both and my hand heled is very sloppy with readings.
Just my experience. I trust the optical unit.

No, I have the hanna handheld:

Haha. I tested many Hanna’s to a few difrent refractometers and hanna is always .002 low. I picked the middle and went with it.

 

[Crabby48]

I’ll added I have a Digital Milwaukee’s refractometer and it reads The same as for other refractometer‘s. Hannah might be more accurate but the Reef standard is refractometer values. Make sense?

That is why I asked. Mine drifts fast. I trusted it for a while without calibrating it and... well that was a mistake.
If you stay on it it really is great.

I would bet a bottle of 2013 The Yamazaki Sherry Cask that it is off by over 2ppt for most users (51%) that have not calibrated within the last two weeks.

I think they are the exact same product just rebranded.

Kind of. So between @Sean Clark and @Crabby48, would you make any particular recommendation in terms of accuracy?

Pick one and stick with it. I set my salinity at 1.025 with Hanna and 1.027 with a refractometer. My lfs has amazing coral they use hanna at 1.026. Other friends kepp salinity with Hanna 1.023 with amazing tanks.

I would have to agree that consistently within a range is more important than accuracy.

It is that whole accuracy precision consistently triangle.

Pick one and use it... but if it the Hanna pen... make sure it is calibrated often.

 

[Sean Clark]

I do have a sealed container of HI7037M and HI70436M if you want to put that Yamazaki 13 up...

Mine never loses calibration. I don’t rinse it and if I do it’s nasty tap water.

The Hanna pen? Maybe I just got a lemon?.

 

[Ugin]

Fair enough. I'll stick with my hanna pen then with occasional checks on the refractometer.

Yes hanna pen. I may have got the odd ball as many say they have issues.

You don’t always need to calibrate it but put pen in solution shake bubbles and see what it reads. Then you will know how far off it is before you calibrate it. If it needs calibration remove from packet hit calibration then stick back in solution. I do float the cal solution in sump before I use it. That is where the temp/salinity part comes to play

 

[Sean Clark]

No, I have the hanna handheld:

Yeah that what I mean. It is never what I say, always what I mean to say...

That's pretty much exactly what I do (heating the solution in the sump, shaking to remove bubbles). Good to know I'm not crazy.

@Sean Clark Also I'm sorry, if I had a yama sherry cask I'd be hiding that away from everyone except for me

 

[Crabby48]

I didn’t say your not crazy. I am nuts

You miss every shot you don't take... I saw some Yama on on those shelves.

Good eyes! I have...
- Yama 12
- Hakushu 12
- Hibiki 21
- Chichibu 2019 + 2020 (US Edition)

Those are the notables. I have things like Nikka 12 which isn't made anymore, but the ones above are the *chefs kiss* good ones
