API Master Kit vs. Tetra Laborette
The API has a nitrate test that the Tetra doesn't and the Tetra has the GH/KH that the API does not. So either way I'll have to buy one more item.
It looks like the API has a high and low range PH with seperate bottles. Looks like the Tetra is a broad range, but I am not sure. And also not sure if it makes a difference.
I keep hearing that Nitrate tests aren't reliable so that would sway me to the Tetra kit so I could find a better Nitrate test if the API isn't adequate. However, it's not like I'm going to spend Lamotte money to get the Nitrate so it would be a matter of a Hagen, Nutrafin, etc... Nitrate test.
