hyposalinity and refractometer ?s

[stinger]

hi guys,
Just a couple of questions about hyposalinity, what sort of level do you recommend? there are seems to be a few different recommendations
(between 1.009 - 1.015).
An article which i got the link from this forum says 1.009-1.010 (78-80 F) or 16 ppt. which brings me to the next question, regarding my refractometer which shows 14ppt to be the same as 1.011. which one is the correct one? should i use the ppt or the other scale (and also at what level)?
i believe this has got something to do with the temperature of the calibration but am not sure.

thanks

I always run my hypo at 14ppt on my refractometer. I don't even look at specific gravity.

hey SteveNichols,
just curious, does your refractometer also shows 14 ppt to be ~1.011 on the other scale too?
Thanks

so far from the refractometer, my SG is 1.013 (equates to 17ppt on the other scale).
do i go lower to 14ppt or 12ppt (1.011 or 1.009 SG respectively according the the refractometer scale)? any suggestion? i'm really lost now

I will look tonight when I get home. Perhaps this article will help: http://www.advancedaquarist.com/2006/3/aafeature1/view?searchterm=hyposalinity. Terry has been around for a lot of years and is basically the guy that "introduced" hypo treatment to many on the boards years ago.
