I personally use Kent Marine SuperBuffer DKH, and I have found that I also have to use a Calcium Chloride supplement to keep the calcium levels where I want them to be. I use Kent Marines liquid calcium for this. So, in some ways, I am using a 2 part additive as well. Which is why the B-ionic product is probably best for beginners.
Just realize, when using B-ionic, if your calcium is low and your alkalinity is high, you don't add both parts. You only add the part that boosts Calcium Chloride. Adding both parts will keep the ratio's of all the major and minor buffering ions correct, provided they are correct to begin with! (This sounds like one of Byron's live plant threads....)
I wrote a nice article on alkalinity and calcium buffering that may help with details. Yes, I just complimented myself, but whatever. http://www.tropicalfishkeeping.com/m...-marine-33079/
By the way, I agree with Wake, a pH buffer can be a nightmare in a marine tank!
