Ca discovery

[rickjames]

I have also been trying to up my Ca in my tank, but hadn't tested my new IO water. Mixed up some last night at 1.025 and test it today... 330ppm Ca!

This is out of a bucket I bought at J&L about a month ago.

I read a post by Anthony Calfo that IO makes their salt so that it mixes up to the right levels with an average (don't know what it is) amount of Calcium and Carbonate already in the water, and that if you use RO/DI water you are supposed to add a buffer or something to get the levels up. Does anyone do this? I will try to find the thread on reef central that this was posted to.
