Wow, i'm impressed. Like others have said, nitrate/Phosphate would be nice. But this is ment for all aquariums it seems, for a planted tank this would be nice. I like it though, for 190 bucks it's cheaper than most par testers, and may give you a spectral plot graph according to the comments section.
