Hypo Question?

[saltwatergal]

I just started hypo on my hospital tank for ick. I have a question on the hypo.
The tank now is 1.016 I brought in down over the last 8 hours from 1.022. Kept an eye on the ph.
Over what period of time should you take for the hypo to get down to 1.009. How much should you drop the salinity per water change along with how often should you do the water change without stressing out the fish?
Information would be appreciated.

Best to do small but several incremental water changes. Take a good look at your fish after each water change to assess for stress. They will tell you if you are going too fast. 2 days is a good measure for getting the salinity down.
What are you using to measure salinity?

Thanks for the feedback.
I am using a refractometer.
