my numbers have always been around 420/8dKh. This is with reactor or with kalk. Since I've never used a doser, I cant say that I used 4ml extra Ca with/without. But again, if I did, do I want to save 4ml Ca by using 20ml Mg (numbers made up, no idea what people use).
I can't/won't offer an opinion saying you need or don't, I just find it odd that so many tanks did so well for all the years before Mg came along. Maybe more do better now? I was kind of disappointed that after starting to use it, I didn't see any change in anything. I guess I was hoping for magical growth or something. But for the cost of the ice melt I'm using, I figure I'll just keep adding, mostly because Randy knows more chem than I do
