Salt calculator?

[jonboy]

Randy and all the other experts,

I need to raise the salinity of my tank. It has slowly dropped to 1.021 I generally keep it at 1.025-1.026
Is there a formula or measurement that will tell me how much salt to add for x gallons?
I dont recall seeing that.
In my case, the system has about 700 gals of water.
It would be nice to know about how much to add, instead of adding and testing,adding and testing, etc.
Thanks
Jonboy

I can calculate it for you, or here's a thread where I discuss it, but I haven't written it out as an equation there:

couldn't he just top off with salt water until the value gets up where it should be?

That's what I usually recommend.
