Sohal Tang in QT...need advice...

[perodogo]

I have my Sohal Tang in QT for over 4 weeks now and I'm still uncertain whether I should put him in my main tank. I did the hyposalinity for 3 weeks at 1.009 and I now have the salinity back up to 1.019. The tang looks great and he's eating well. However, I still notice him breathing a little heavier than normal and I see him scraping his body against the glass every now and then. I have never seen any spots on him and other than the occasional scraping and heavy breathing, he seems to be in great shape and very active.
FYI - the QT is 25 gallons and there is one permanent resident - a small percula clown; I do have a refractometer and I have used the hypo technique successfully on my other livestock. Do I start the hypo again?? Please advise...
Thanks.

Well, you need to bring the specific gravity back up to within normal range [the SG of your display tank], then wait a week before putting the fish back into the display.
Does your refract also read salinity? Usually the readings on the right side of the refract? If so, do you recall what the reading was during the hypo procedure?

Yes, it does measure salinity. I had it at 14 ppt.
