Magnesium test

Oh gosh... you'll get 5 different answers by the time this is all done.

I have heard good things about the Seachem test kits. I think I'm getting those for my tank. They're pretty easy to use.
 
I haven't heard anything bad about any of them. I'm going to order an Elos kit soon to see how I like it. I've heard they are easy to use. Currently use Salifert and it is about as easy as any of their other kits.
