I use 1/2 cup per gallon for reef crystals.

How much salt to make 35ppt
Anyone know how much reef crystals I would need to make 4 gallons of 35ppt? I think it is about 1.2 pounds but not sure of exact measurement. Thanks!

years ago it took 41.3 g/L of normal IO to attain 35 ppt, but the result will be different if moisture levels in it are different.
That's 312 g/2 gallons. [edited to correct a math error]

Ive been doing that as a rough guess but I ALWAYS have to add in more than 2.5 cups for 5 gallons and keep creeping up on 35ppt. It would be nice to just measure it out and not have to adjust 2-3 times after the initial batch.I use 1/2 cup per gallon for reef crystals.

You're right, the 41.3 g/L I quoted multiplies up to 312 g/2 gallons or 781 g/5 gallons. Not sure where the multiplication went astray. lol
The salt can often gets heavier once you open the bag. I would use volume over weight. ...ask me how I know? 
I would dry mix that salt, too. Unless I use the whole bag of IO, I can get inconsistent results when using a partial bag or small portion.

I only get single 50 gallon bags of IO at a time and I dump the bag into a 5 gallon bucket with a snap top.The salt can often gets heavier once you open the bag. I would use volume over weight. ...ask me how I know?
