I have a 50 gallon reef that I regularly dose limewater for all top off. This works fairly well to keep up with my calcium, but not quite with the Alk. I have used kalk with B-Ionic in the past with good results, but would like your opinion on what products I should take a look at to make up for the difference in Alk. My tank without anything but kalk will maintain at about 7 dkH, my target is closer to 9 dkH. Thanks in advance for your help on this.
