At Big Als, they sell test kit refills, so if I bought refills instead of a whole kit, and use my own vials, wouldn't I be saving $ than if I was buying a whole kit? This is an example of what I mean: http://www.bigalsonline.com/BigAlsUS/ctl3684/cp18543/si1380452/cl0/nutrafintestkhreagentrefill15ml
And, if I put Kent's Liquid Calcium (it's calcium chloride) into my tank, would I need a KH test to measure it or a calcium test? I already have a GH test, but that won't measure it, right?
