Recipe for hyposalinity please.

So first, thank you quarantine....
It looks like Nemo has ich (tail thinning and fuzzy and a white spot). So tommorrow will start slowly using rodi water to reduce my salinity to 1.009. After that will need to make up water change water.
Is there a guestimate of a recipe for it like there is for 1.026 with 3C for 5 gal?
I am usin IO reef crystals.

Since .009 is approximately one third of .026, you would use approximately one third of the salt...so, in your case, around 1C for 5 gal. Your best bet is to put in a bit less than the guestimate would suggest, measure and then adjust as necessary.

true use 1/3 of the salt and give it some time to clear up then check for salinity, best wait 24 hrs before using, check salinity again at 24hrs.

I ended up experimenting a bit to figure out a recipe. If you add 1/2 cup and your water is at 1.005, two cups should put you at 1.010, but always check!

Two other caveats - don't trust a swing-arm hydrometer. Use either a floating hydrometer or a refractometer and make sure it is calibrated! If you calibrate a refractometer, check it with RO/DI (should be 0) and with calibration solution. If the calibration for the two differs appreciably, I would probably use the RO/DI calibration or try to split the difference, since your goal of 1.009 is closer to 0 than the 1.026 that most calibration solutions use.

Also, make sure you check pH. As the salinity decreases, so do the buffers and your pH may be off significantly. I have to add 2 tbsp of baking soda per 5 gal of water to keep the pH in line. Tank pH can drift, too, so keep an eye on that as well.
