adding kalkwasser

[Southern Boy]

Is it safe to add kalkwasser directly to ro/di water for topoff? If so how much should be added per gallon?

Short answer is yes and here is a good article from Randy Holmes-Farley titled: <a href="http://www.reefkeeping.com/issues/2005-01/rhf/index.php#5" target="_blank">What Your Grandmother Never Told You About Lime</a> which should explain everything better than I could! You may want to look in <a href="http://www.reefcentral.com/forums/forumdisplay.php?s=&forumid=112" target="_blank">The Reef Chemistry Forum</a> for Randy’s other articles. Good luck!
