Wow, this is very nice. Sorry I hadn't seen this post before. I was on a bit of a hiatus from the forums and hobby at the time.
One thing I might mention is that he crushed coral isn't the greatest substitute for the dolomite. It's probably best just to omit it if you can't find it. The dolomite also has Mg and dissolves much slower.
