Best way to start. Of course now I'll be getting the Apex with the salinity probe and prob only use this for a few weeks....

Make sure you calibrate it and not with rodi water.

I was one of those that purchased a bad one from amazon. I used ro/di to calibrate during hyposalinity treatment and ended up losing a very expensive fish.
Now, I calibrate using 53 mS test fluid, it calibrates at 35 ppt and noticed that my refractometer is defected and it needs to be calibrated every time I need to use it.

that means you'll have to also have a refrac no, or have someone close by with one?
It may say that, but- not as accurate.
Here is a great article from RHF discussing the difference.
(I have the red sea & it says to calibrate with rodi and I've done comparison between that & the solution, I tell you it's pretty far off using rodi).
You want the calibration mark closest to the solution, (salt water), as possible.

Any of my lfs, which I like to frequent and support anyway. Have had the same float meter for years. Have tested it anytime I've had to do hypo, and every time it's been exactly 1 point under what the level actually is.

It does say to use distill but its bad advise. Use the calibration solution for seemless use. Using distilled or rodi will have your refractometer off by quite a bit!

Wayne,
Use calibration solution-for peace of mind
I do, and also recalibrate every 3 months
( 1bottle will last you a very long time )

Where can I pick this up, I didn't see it on amazon when I placed my order. (Truthfully I wasn't looking)
