salt problem

[nate9]

i have a bit of a problem here with my new salt, i just went out and purchased some Red Sea salt, got home and decided to do a water change on my 20 gallon. I do a 2 gallon water change but when i looked on the back of the container to see how much salt i am susposed to use for some odd reason they have the amount you are susposed to use in pounds!?! Now why on earth would they do that, i do not have a scale around my house to measure the correct amount so i do not knwo what to do. Then to make matters worse they only have the amount you are to use in 5 gallon segments. I relize there is simple math involved to find the amount i need for 2 gallons and that comes out to .56 pounds for 2 gallons but the problem is, as i have learned from past expirence, the amount you are to use is not always proportional. So i guess what i need is if anyone knows of a converstion chart for Red Sea salt or if anyone uses that salt and has already done the work. thanks for any help

no one uses Red Sea salt here and has never had to do this before??

I use about 2.5 cups per gallon and that gets me to about 1.025sg. I'd start with that amount and then test the specific gravity. Then, adjust as necessary.
