Ca was 460ppm yesterday, dKH was 8 & MG 1400ppm, I haven't noticed any problems with the tank... Does any one else keep their salinity this high?

460 is on the high side, unless your using a lot of additional Ca, that might be from the salinity being too high. 1.030 is too high, but the easiest thing to do is take a sample to the LFS or a buddy with a tank and check it a third time.

You should lower your salinity to 1.024-1.026. Do it very slowly.
What brand of salt mix you use? If you lower your salinity the ca level will drop accordingly. I recommend you check these parameters on weekly base: Salinity, ca, alk, mg, po4, no3. Keep it on excel chart so you can identify if your system develop some tendency to go to the wrong direction.

I use Reef Crystals, My SPS at the moment consume my Ca fairly rapidly I had been looking to maintain salinity at around 35ppt or SG at 1.025 / 80f degrees.. All other parameters are great . Thanks for the reply. S

I've compared several hydrometers with my refractometer and I've seen some that were out as much as 0.006.
I also use a sample of known salinity to calibrate my refractometer yearly http://www.jlaquatics.com/product/pp...+Solution.html so I feel confident that I'm getting accurate results.

OK I will go against the flow. I think it is another toy for the boys. But each to his own.
My son has one. I never use it because it is a little difficult to use compared to a cleaned after use hydrometer. If you don't clean it after use the refractometer will be off and if you don't clean the water test kits your tests will be off too. I couldn't go through the picky calibration required by a refractometer and go to the trouble of buying the calibration solution before it gets stale and all that stuff. I wonder how many reefers who own them go through the calibration stuff or simply just use it? It is easier to simply plunge the hydrometer in the tank and scoop up the water to be tested and viola, you are bang on again. (and clean it after use) Take a look at the this thread in advanced acquarist. It seems to confirm what I have posted. http://www.advancedaquarist.com/2006...=refractometer
