aragaMIGHT!

nevermind apparently it is not just a freshwater thing...I'm not sure why you would use it. Its just crusehd coral, its more of a buffer boost then something to use with RO. SHould increase pH and Alk.
 
It has a good bit of calcium, carbonate, strontium, Mg, and Potassium. Don't know if I want to use it or not. I know it should be good for the price.
