howto get a refractometer reading of 1.005 in salt solutiom|how to measure salinity : discounter It seems to depend on how I calibrate my refractometer. I have always used RO/DI but I recently bought some calibration solution which is 35ppt or 1.026. When I use RO to . To prepare 1 L of 1 M MgCl 2, dissolve 203.3 g of MgCl 2 •6H 2 O in 800 mL H 2 O. Adjust the .I have a protocol with a SOB receipt that said autoclave the solution before adding MgCl2 and MgSO4. I just wondering if autoclave will destroy these two compounds, or is there .

It seems to depend on how I calibrate my refractometer. I have always used RO/DI but I recently bought some calibration solution which is 35ppt or 1.026. When I use RO to calibrate, my tank is currently 1.008 but if I use the calibration solution, it is 1.005.
Using the same 35 ppt reference solution, turn the calibration adjustment screw until the refractometer reads correctly at 35 ppt. Rinse the lens and then proceed to measure your tank water. By going through this two-step verification and calibration, you can be confident your measurements are accurate. Here's a shot of it with calibration ro/di before temperature stabilization so you can see what you would think of trying to read the difference in 1.005 and 1.010. If I ran a reef, I would likely set up a suite of the Hanna digital meters and their associated calibration gear/liquids, the cost of setting up a good reef would justify it to me.
When using a conventional ‘saltwater’ or ‘brine’ refractometer for the reef aquarium we must therefore look to achieve a reading of 36.8ppt if our intended salinity is 35ppt or 37.3ppt if our intended salinity is 35.5ppt as quoted for the H2Ocean salt. As others have said, check the refractometer before you make any changes. My favorite method to correct low salinity is to add via ATO. Seems to be gradual enough not to shock anything.
Hi all i have just tested the S.G in my tank and the result was, 1.005, this surely can not be correct, i mixed the salt at 1.025 just a few days ago when.Refractometers are the most common tool used by aquarists. Place a few drops of aquarium water on the viewing prism, close the lid and look through the eyepiece. Where the blue and white areas meet is the salinity reading of the aquarium water – 1.024 SG or 30% is the ideal salinity.
Well after more than a year of continuos use of my marinedepot refractometer which was calibrated more than a year ago with one of those special calibrating liquids I got a reading of 1.005 with new RO/DI water. :mad2:
Refractometer: Start by maintaining the device at 20°C for about 30 minutes. Clean its glass screen thoroughly. Place the correct amount of calibration fluid to cover the screen and close the lid. Look through the eyepiece and note the reading. Adjust the refractometer if it’s not showing 34 to 36 PPT.Salt Mix Calculator. Enter the water volume (in gallons) and select your salt mix from the list. Enter the current salinity level PPT as well as your desired salinity level to find out how much salt mix will be required to reach the desired salinity.
