Well....after reading the excellent article by Randy on how to calibrate your refractometer, I decided, sure sounds good to me. So I chugged half a 2 litre bottle of Pepsi so I could have the requisite container for the calibration mix. After carefully measuring the proper amount of salt, and thoroughly mixing it all up, I casually dripped a couple of drops on my nice expensive refractometer that I bought a couple of months ago. Now I take a peek through the eyepiece, thoroughly expecting to see 1.026 or 35ppt, take your pick. But what do I see.....1.020 or about 26ppt!!! No way I say....and mix another batch of calibration solution. Same result. So I dust of my cheap little swing arm hydrometer, and bingo...1.026....right on the nose. After I got done cursing, I re-calibrated and triple checked the refractometer. Now comes the moment of truth, as I grab a water sample from my tank and check it with the refractometer. I take a peek, and 1.019 is staring back at me! Off to the hydrometer I go to double check....sure enough....1.019.
Thanks for hanging around to read the long winded narrative....and here is my question: I have spent the last couple of days dripping the correct salinity water into my tank to slowly raise it to my targer of 1.026 or 35ppt. No one in the tank seems to mind, except the BTA. I have included a couple of pics to show you what I mean. Comments or suggestions would be greatly appreciated.

so we added the 75. Simple is a good way to go! 40 is going to be more stable than 12 that's for sure!
